DESCRIPTION
The L296 and L296P are stepdown power switching
regulators delivering 4 A at a voltage variable from
5.1 V to 40 V.
Features of the devices include soft start, remote in-
hibit, thermal protection, a reset output for micro-
processors and a PWM comparator input for syn-
ch ron iz at io n in m ult ic h ip c onf ig ur at ion s.
T he L296P inc udes e xtern al prog rammab le lim iting
current.
The L296 and L296P are mounted in a 15-lead Mul-
tiwatt plastic power package and requires very few
exter nal c om ponents.
Efficient operation at switching frequencies up to
200 KHz allows a reduction in the size and cost of
external filter components. A voltage sense input
and SCR drive output are provided for optional
crowbar overvoltage protection with an external
SCR.

N°Name Function
1 CROWBAR INPUT Voltage Sense Input for Crowbar Overvoltage Protection. Normally connected to the
feedback input thus triggering the SCR when V out exceeds nominal by 20 %. May
also monitor the input and a voltage divider can be added to increase the threshold.
C onnected to ground when SCR not used.
2 OUTPUT Regulator Output
3 SUPPLY VOLTAGE Unrergulated Voltage Input. An internal Regulator Powers the L296s Internal Logic.
4 CURRENT LIMIT A resistor connected between this terminal and ground sets the current lim iter
threshold. If this terminal is left unconnected the threshold is internally set (see
electrical characteristics).
5 SOFT START Soft Start Time Constant. A capacitor is connected between this terminal and ground
to define the soft start time constant. This capacitor als o determines the average
short circuit output current.
6 INHIBIT INPUT TTL – Level Remote Inhibit. A logic high level on this input disables the device.
7 SYNC INPUT M ultiple L296s are synchronized by connecting the pin 7 inputs together and omitting
the oscillator RC network on all but one device.
8 GROUND Common Ground Terminal
9 FREQUENCY
COMPENSATION A series RC network connected between this terminal and ground determines the
regulation loop gain characteristics.
10 FEEDBACK INPUT T he Feedback Terminal on the Regulation Loop. The output is connected directly to
this terminal for 5.1V operation ; it is connec ted via a divider for higher voltages.
11 OSCILLATOR A parallel RC networki connected to this terminal determines the switching frequency.
T his pin must be connected to pin 7 input when the internal oscillator is us ed.
12 RESET INPUT Input of the Reset Circuit. The threshold is roughly 5 V. It may be connected to the
feedback point or via a divider to the input.
13 RESET DELAY A capacitor connected between this terminal and ground determines the reset signal
delay time.
14 RESET OUTPUT Open collector reset signal output. This output is high when the supply is safe.
15 CROWBAR OUTPUT SCR gate drive output of the crowbar circuit.

CIRCUI T OPERATION
(refer to the block diagram)
The L296 and L296P are monolithic stepdown
sw it c hing re gulators pr ov iding out pu t v oltages fr om
5. 1V to 40V and delive ri ng 4A .
The regulation loop consists of a sawtooth oscillator,
error amplifier, comparator and the output stage. An
error signal is produced by comparing the output
voltage with a precise 5.1V on-chip reference (zener
zap trimmed to ± 2 %). This error signal is then com-
pared with the sawtooth signal to gen erate the fixed
frequency pulse width modulated pulses which drive
the output stage. The gain and frequency stability of
the loop can be adjusted by an external RC network
connected to pin 9. Closing the loop directly gives an
output voltage of 5.1V. Higher voltages are obtained
by ins er ti ng a v ol ta ge di vi der .
Output overcur rents at s witch on are prevented by
the sof t st art function. The error amplifier output is
initially clamped by the external capacitor Css and
allo wed to ris e, line arly , as t his capacit or i s char ged
by a constant current source.
Output overload protection is provided in the form of
a current limiter. The load current is sensed by an
internal metal resistor connected to a comparator.
When the load current exceeds a preset threshold
this comparator sets a flip flop which disables the
output stage and discharges the soft start capacitor.
A second comparator resets the flip flop when the
volta ge acro ss th e soft st art capaci to r has fall en to
0.4V. The output stage is thus re-enabled and the
output voltage rises under control of the soft start
netw ork. If the o verload c onditio n is sti ll p resent the
limiter will trigger again when the threshold current
is reached. The average s hort circuit current is lim-
ited to a safe v alu e by the dead time int ro duc ed by
the sof t star t network.
The reset circuit generates an output signal when
the supply voltage exceeds a threshold pro-
gram med by an exte rnal d ivide r. The re set si gnal is
gener ated wi th a delay tim e prog rammed by an ex -
ternal capacitor. When the supply falls below the
threshold the reset output goes low immediately.
The res et output is an open colle ctor.
The scr owbar ci rcui t s enses t he output vol tage an d
the cr owbar output can prov ide a current of 100mA
to switch on an external SCR. This SCR is triggered
when the output voltage exceeds the nominal by
20%. There is no internal connect ion between t he
outpu t and cr owbar sense i npu t th erefore the crow -
bar c an m oni to r ei ther th e inp ut or the out put.
A TT L - level in hibit input is provided for ap plications
such as remote on/off control. This input is activated
by hig h logic le vel and disables circuit operation. Af-
ter an inhibit the L296 restarts under control of the
soft start network.
The thermal overload circuit disables circuit opera-
tion when the junction temperature reaches about
150 °C and has hys teres is to pre vent un stable c on -
ditions.

SOFT -START AND REPETITIVE POWER-ON
When the device is repetitively powered-on, the soft-
star t capaci to r, CSS, must be discharged rapidly to
ensure that each start is "soft". This can be achieved
economically using the reset circuit, as shown in Fig-
ure 44 .
In this c ircuit the di vider R1, R2 c onnec ted t o pin 12
determines the minimum supply voltage, below
which the open c ollector transistor at the pin 14 out-
put dis ch ar ges CSS.

If these times are still too long, an external PNP tran-

HOW T O OBTAI N BOTH R ESET A ND
POWE R FAI L
Figure 46 illustrates how it is possible to obtain at the
same t ime both the power fail and reset functions
simply by adding one diode (D) and one resistor (R).
In this case the Reset delay time (pin 13) can only
star t w hen the o ut put voltage is V O ≥ VREF - 100 mV
and t he v oltage acc ro ss R2 is higher than 4. 5V .
With the hy steresis resistor it is p ossible to fix the in-
put pin 12 hysteresis in order to increase immunity
to the 1 00Hz ripp le pr es en t o n the s upply vol tage.
Moreover, the power fail and reset delay time are
aut om atic ally loc k ed to the sof t-s tar t . S of t-s tar t and
delay ed reset ar e thus t wo se quential fun ctions.
The hysteresis resistor should be In the range of
aboit 100 kΩ and th e pul l- up r es is tor of 1 to 2.2 kΩ.
