PIN CONFIGURATION
PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
1
HSB
High Side Bias Pin. This provides power to the internal high-side MOSFET gate driver.
Connect a 22nF capacitor from HSB pin to SW pin.
2
IN
Power Supply Input. Bypass this pin with a 10µF ceramic capacitor to GND, placed as
close to the IC as possible.
3 SW Power Switching Output to External Inductor.
Ground. Connect this pin to a large PCB copper area for best heat dissipation. Return
4
GND
FB, COMP, and ISET to this GND, and connect this GND to power GND at a single
point for best noise immunity.
5
FB
Feedback Input. The voltage at this pin is regulated to 0.808V. Connect to the resistor
divider between output and GND to set the output voltage.
6
COMP
Error Amplifier Output. This pin is used to compensate the converter.
Enable Input. EN is pulled up to 5V with a 4μA current, and contains a precise 1.6V
7 EN logic threshold. Drive this pin to a logic-high or leave unconnected to enable the IC.
Drive to a logic-low to disable the IC and enter shutdown mode.
8
ISET
Output Current Setting Pin. Connect a resistor from ISET to GND to program the
output current.
Exposed Pad
Heat Dissipation Pad. Connect this exposed pad to large ground copper area with
copper and vias.
