Performance
Characteristic
The XC6367/68 series are multi-functional step-up DC/DC converter
controllers with built-in high speed, low ON resistance drivers.
Large output currents are possible using an externally connected
transistor, coil, diode and condenser.
Output voltage is selectable in 0.1 steps within a 1.5V ~ 6.5V range
(±2.5%). For output voltages outside this range, we recommend this FB
version, which has a 1.0V internal reference voltage. Using this version,
the required output voltage can be set-up using 2 external resistors.
With a 300kHz switching frequency, the size of the external components
can be reduced.
Control switches from PWM to PFM during light loads with the XC6368
(PWM/PFM switchable) and the series is highly efficient from light loads
to large output currents.
Soft start time of XC6367/68A, B, and C series is internally set to
10msec and XC6367/68C, D, and F series regulate soft start time by
connecting resistors and capacitors exteranally.
During stand-by time (CE pin "Low"), current consumption is reduced to
less than 0.5µA.
Input voltage range : 0.9V~10V
Operating voltage range : 2.0V~10V
Output voltage range : 1.5V~6.5V programmable in 0.1V
steps (±2.5%)
Oscillator frequency : 300, 100kHz (±15%)
Custom products for 180, 500kHz
Output Current : 200mA + (VIN=1.8V, VOUT=3.3V)
High Efficiency : 84% (typ.)
Stand-by capability :ISTB=0.5A (max.)
Selection : Soft start set-up external
Output Voltage set-up internal (VOUT)

If you wish to lengthen soft start time we recommend that you use the C or D versions of the series which
have soft start time externally set up.
Soft start time (TSS) is between MIN & MAX, as indicated in the graphs below, so please select soft start
condenser capacitance (CSS) to suit your application.
In order to achieve a value for fzfb within the range of 0.1kHz to 20kHz, we recommend that values for
RFB1 & CFB are selected from the area indicated within the lines of fzfb = 0.1kHz and fzfb = 20 kHz as
shown on the graph below. Please select combinations of values as close to the fzfb = 10kHz line as possible.
●External Components
■Directionsforuse
●Notes on Use
Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are exceeded.
Be extremely careful when selecting parts and do not limit your reference to the specifications and characteristics for the DC/DC converter
alone. The IC also depends, to a great extent, upon the external components.
Arrange the peripherals in the environs of the IC. In order to reduce wiring impedance, use short, thick wires. In particular, wire the load
capacitor as close as possible and strengthen the ground wiring sufficiently.
Ground current during switching may cause the IC's operations to become unstable due to changes in ground voltage, so please strengthen the
IC's GND pin surroundings.
