DESCRIPTION
The supply input pin is a terminal for an unregulated input voltage source. It is required
to place the input capacitor nearby the VIN pin and PGND.
SYNC
EN
The Sync input pin allows for synchronization of the PWM operating frequency with an
2
Input external frequency source. Apply a CMOS logic level square wave with a frequency
between 650 kHz and 950 kHz. When not using synchronization connect to ground.
The module free running PWM frequency is 812kHz (typical).
Connecting this pin to GND disables the device. Connecting this pin to a voltage

Input
higher than 1.18V typ. (but <6.5V) or leaving it floating enables the device. This pin
can be used in order to set an external UVLO through a resistor divider. If this pin is
left floating the device is always on.
AGND
4
Supply
The analog ground pin is the reference point for all stated voltages and must be
connected to PGND.
The feedback pin is internally connected to the regulation circuitry, the over-voltage
FB
5
Input and short-circuit comparators. The regulation reference point is 0.796V at this input
pin. Connect the feedback resistor divider between the output and AGND with the
midpoint at this pin to set the output voltage.
The Soft-Start and Tracking pin is to extend the 1.6ms internal soft-start by connecting
SS/TRK
6
Input an external soft-start capacitor. To enable voltage tracking connect to an external
resistive divider connected to a higher priority supply rail.
VOUT

Power
The output voltage pin is connected to the internal inductor. For the best stability and
operation connect the output capacitor between this pin and PGND.
PGND
Exposed Pad - Main node for switch current of internal low-side MOSFET. Used as
EP
Power heat sink for power dissipation during operation. Must be electrically connected to pin
4.
