PIN FUNCTIONS
Pin # Name Description
1 NC Not Connected.
2 V
CC
Low-Side Driver Bias Supply. Decouple with a 1µF ceramic capacitor.
3 AGND Signal Ground.
4 EN
Active High On/Off Control. Pulling this Pin Low forces the SW Pin to be in a high
impedance state.
5 SYNC
Leaving this pin Open enables theLower Synchronous Switch. Pulling it Low forces
the Lower Switch into Diode Emulation mode.
6 PWM
Pulse Width Modulation Control. Accepts three-state input. Force PWM to midstate or
open to place SW into high impedance state.
7 V
CC
IO Reference voltage that connects to PWM driver supply.
8 BST
Bootstrap. This capacitor is needed to drive the power switch’s gate above the supply
voltage. It is connected between SW and BST pins to form a floating supply across
the power switch driver.
9
Exposed Pad
IN
Supply Voltage. C
IN
is needed to prevent large voltage spikes from appearing at the
input.
10–18
Exposed Pad
GND Power Ground.
Exposed Pad SW Switch Output. These pins are fused together.
