DETAILED OPERATIONAL DESCRIPTION
PWM Input with Tri-State Function
The PWM input receives the PWM control signal from the VR
controller IC. The PWM input is designed to be compatible
with standard controllers using two state logic (H and L) and
advanced controllers that incorporate tri-state logic (H, L
and tri-state) on the PWM output. For two state logic, the
PWM input operates as follows. When PWM is driven above
VPWM_TH_R the low-side is turned off and the high-side is
turned on. When PWM input is driven below VPWM_TH_F the
high-side is turned off and the low-side is turned on. For
tri-state logic, the PWM input operates as previously stated
for driving the MOSFETs when PWM is logic high and logic
low. However, there is a third state that is entered as the
PWM output of tri-state compatible controller enters its high
impedance state during shut-down. The high impedance
state of the controller’s PWM output allows the SiC533 to
pull the PWM input into the tri-state region (see definition of
PWM logic and tri-state, Fig. 4). If the PWM input stays in
this region for the tri-state hold-off period, tTSHO, both
high-side and low-side MOSFETs are turned off. The
function allows the VR phase to be disabled without
negative output voltage swing caused by inductor ringing
and saves a Schottky diode clamp. The PWM and tri-state
regions are separated by hysteresis to prevent false
triggering. The SiC533 incorporates PWM voltage
thresholds that are compatible with 5 V logic.
Diode Emulation Mode and PS4 Mode (ZCD_EN#)
The ZCD_EN# pin enables or disables diode emulation
mode. When ZCD_EN# is driven below VTH_ZCD_EN#_F, diode
emulation is allowed. When ZCD_EN# is driven above
VTH_ZCD_EN#_R, continuous conduction mode is forced.
Diode emulation mode allows for higher converter efficiency
under light load situations. With diode emulation active, the
SiC533 will detect the zero current crossing of the output
inductor and turn off the low-side MOSFET. This ensures
that discontinuous conduction mode (DCM) is achieved.
Diode emulation is asynchronous to the PWM signal,
therefore, the SiC533 will respond to the ZCD_EN# input
immediately after it changes state.
The ZCD_EN# pin can be floated resulting in a high
impedance state. High impedance on the input of ZCD_EN#
combined with a tri-stated PWM output will shut down the
SiC533, reducing current consumption to typically 5 μA.
This is an important feature in achieving the low standby
current requirements required in the PS4 state in ultrabooks
and notebooks.
Voltage Input (VIN)
This is the power input to the drain of the high-side power
MOSFET. This pin is connected to the high power
intermediate BUS rail.
Switch Node (VSWH and PHASE)
The switch node, VSWH, is the circuit power stage output.
This is the output applied to the power inductor and output
filter to deliver the output for the buck converter. The PHASE
pin is internally connected to the switch node, VSWH. This pin
is to be used exclusively as the return pin for the BOOT
capacitor.
Ground Connections (CGND and PGND)
PGND (power ground) should be externally connected to
CGND (control signal ground). The layout of the printed circuit
board should be such that the inductance separating CGND
and PGND is minimized. Transient differences due to
inductance effects between these two pins should not
exceed 0.5 V.
Control and Drive Supply Voltage Input (VDRV, VCIN)
VCIN is the bias supply for the gate drive control IC. VDRV is
the bias supply for the gate drivers. It is recommended to
separate these pins through a resistor. This creates a low
pass filtering effect to avoid coupling of high frequency gate
drive noise into the IC.
Bootstrap Circuit (BOOT)
The internal bootstrap diode and an external bootstrap
capacitor form a charge pump that supplies voltage to the
BOOT pin. An integrated bootstrap diode is incorporated so
that only an external capacitor is necessary to complete the
bootstrap circuit. Connect a boot strap capacitor with one
leg tied to BOOT pin and the other tied to PHASE pin.
Shoot-Through Protection and Adaptive Dead Time
The SiC533 has an internal adaptive logic to avoid shoot
through and optimize dead time. The shoot through
protection ensures that both high-side and low-side
MOSFETs are not turned on at the same time. The adaptive
dead time control operates as follows. The high-side and
low-side gate voltages are monitored to prevent the
MOSFET turning on from tuning on until the other
MOSFET’s gate voltage is sufficiently low (< 1 V). Built in
delays also ensure that one power MOSFET is completely
off, before the other can be turned on. This feature helps to
adjust dead time as gate transitions change with respect to
output current and temperature.
Under Voltage Lockout (UVLO)
During the start up cycle, the UVLO disables the gate
drive, holding high-side and low-side MOSFET gates low,
until the supply voltage rail has reached a point at which
the logic circuitry can be safely activated. The SiC533 also
incorporates logic to clamp the gate drive signals to zero
when the UVLO falling edge triggers the shutdown of the
device.

PCB LAYOUT RECOMMENDATIONS
Step 1: VIN / PGND Planes and Decoupling
1. Layout VIN and PGND planes as shown above.
2. Ceramic capacitors should be placed directly between
VIN and PGND, and close to the device for best
decoupling effect.
3. Different values / packages of ceramic capacitors should
be used to cover entire decoupling spectrum e.g. 1210,
0805, 0603, 0402.
4. Smaller capacitance values, placed closer to the
device’s VIN pin(s), results in better high frequency noise
absorbing.
Step 2: VSWH Plane
1. Connect output inductor to IC with large plane to lower
resistance.
2. VSWH plane also serves as a heat-sink for low-side
MOSFET. Make the plane wide and short to achieve the
best thermal path.
3. If a snubber network is required, place the components
as shown above, the network can be placed at bottom.
Step 3: VCIN / VDRV Input Filter
1. The VCIN / VDRV input filter ceramic cap should be placed
as close as possible to the IC. It is recommended to
connect two capacitors separately.
2. VCIN capacitor should be placed between pin 2 (VCIN)
and pin 3 (AGND of driver IC) to achieve best noise
filtering.
3. VDRV capacitor should be placed between pin 20
(PGND of driver IC) and pin 21 (VDRV) to provide maximum
instantaneous driver current for low side MOSFET during
switching cycle.
4. For connecting VCIN to AGND, it is recommended to use
a large plane to reduce parasitic inductance.
Step 4: BOOT Resistor and Capacitor Placement
1. The components need to be placed as close as possible
to IC, directly between PHASE (pin 5) and BOOT (pin 4).
2. To reduce parasitic inductance, chip size 0402 can be
used.

Step 5: Signal Routing
1. Route the PWM and ZCD_EN# signal traces out of the
top left corner next to pin 1.
2. The PWM signal is an important signal, both signal and
return traces should not cross any power nodes on any
layer.
3. It is best to “shield” these traces from power switching
nodes, e.g. VSWH, with a GND island to improve signal
integrity.
4. GL (pin 19) has been connected with GL pad (pin 24)
internally.
Step 6: Adding Thermal Relief Vias
1. Thermal relief vias can be added on the VIN and AGND
pads to utilize inner layers for high-current and thermal
dissipation.
2. To achieve better thermal performance, additional vias
can be placed on VIN plane and PGND plane.
3. VSWH pad is a noise source, it is not recommended to
place vias on this pad.
4. 8 mil vias for pads and 10 mils vias for planes are the
optimal via sizes. Vias on pad may drain solder during
assembly and cause assembly issues. Consult with the
assembly house for guidelines.
Step 7: Ground Connection
1. It is recommended to make a single connection between
AGND and PGND which can be made on the top layer.
2. It is recommended to make the entire first inner layer
(below top layer) the ground plane and separate them
into AGND and PGND planes.
3. These ground planes provide shielding between noise
sources on top layer and signal traces on bottom layer.
