PIN DESCRIPTION
1
V
IN
Power
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.
2
SYNC
Input
The Sync Input pin allows to synchronize the PWM operating frequency to an
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).
3
EN
Input
The enable input pin is internally connected to the precision enable comparator
and the rising threshold is at 1.18V. Maximum recommended input level is 6.5V.
4
AGND
Supply
The analog ground pin is the reference point for all stated voltages and must be
connected to PGND.
5
FB
Input
The feedback pin is internally connected to the regulation circuitry, the over-
voltage 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 to set the output voltage.
6
SS/TRK
Input
The Soft-Start and Tracking pin is to extend the 1.6ms internal soft-start.
Connect an external soft start capacitor. For tracking connect to an external
resistive divider connected to a higher priority supply rail.
7
V
OUT
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.
EP
PGND
Power
Exposed Pad – Main node for switch current of internal LS-MOSFET. Used as
heat sink for power dissipation during operation. Must be electrically connected
to pin 4.
