PIN DESCRIPTIONS
PIN# PIN SYMBOL PIN DESCRIPTION
1
VGATE
Output driver for external P Channel MOSFET.
2
Gnd
This pin serves as ground pin and must be connected to the ground plane.
3
VSEN
A resistor divider from this pin to VOUT and Vcc or an external VREF, sets the output
voltage.
4
ISEN
This pin sets the maximum load current by sensing the inductor current.
5
VDD
This pin provides biasing for the output driver.
6
Vcc
This pin provides biasing for the internal blocks of the IC.
