Pin 1: V
DD
The positive power supply for all functional blocks except
output driver. A bypass capacitor of 0.1 F (minimum) is
recommended.
Pin 2: N/C
There is no internal connection to this pin.
Pin 3: D
MAX
Used to set the maximum duty cycle.
Pin 4: COMP
This pin is the output of the error amplifier. A compensation
network is connected from this pin to the FB pin to stabilize the
system. This pin drives one input of the internal pulse width
modulation comparator.
Pin 5: FB
The inverting input of the error amplifier. An external resistor
divider is connected to this pin to set the regulated output
voltage. The compensation network is also connected to this
pin.
Pin 6: NI
The non-inverting input of the error amplifier. In normal
operation it is externally connected to V
REF
or an external
reference.
Pin 7: V
REF
This pin supplies a 1.5-V reference.
Pin 8: GND (Ground)
Pin 9: ENABLE
A logic high on this pin allows normal operation. A logic low
places the chip in the standby mode. In standby mode, normal
operation is disabled, supply current is reduced, the oscillator
stops, and D
S
goes low while D
R
goes high.
Pin 10: R
OSC
A resistor connected from this pin to ground sets the
oscillator’s capacitor (C
OSC
) charge and discharge current.
See the oscillator section of the description of operation.
Pin 11: C
OSC
An external capacitor is connected to this pin to set the
oscillator frequency.

(at V
DD
= 5.0 V)
Pin 12: UVLO
SET
This pin will place the chip in the standby mode if the UVLO
SET
voltage drops below 1.2 V. Once the UVLO
SET
voltage
exceeds 1.2 V, the chip operates normally. There is a built-in
hysteresis of 200 mV.
Pin 13: P
GND
The negative return for the V
S
supply.
Pin 14: D
S
This CMOS push-pull output pin drives the external n-channel
MOSFET. This pin will be low in the standby mode. A
break-before-make function between D
S
and D
R
is built-in.
Pin 15: D
R
This CMOS push-pull output pin drives the external p-channel
MOSFET. This pin will be high in the standby mode. A
break-before-make function between the D
S
and D
R
is built-in.
Pin 16: V
S
The positive terminal of the power supply which powers the
CMOS output drivers. A bypass capacitor is required.
