Pin Description

Inductor input. Inductor L connected between this pin and the battery

Connect directly to battery

Low battery detect input and shutdown. Low battery detect threshold is set with this pin

using a potential divider. If this pin is pulled to logic low then the device will shutdown.

A logic level signal referenced to VIN, at a frequency between 150kHz and 500kHz on

this pin will override the internal 300kHz oscillator. If the SYNC function is unused then

pin 4 should be connected to ground

This open drain output pin will go high when output voltage is within regulation,

0.92*VOUT (NOM) < VOUT < 0.98*VOUT (NOM)

This pin sets the adjustable output voltage via an external resistor divider network. The

formula for choosing the resistors is shown in the “Applications Information“ section.

This open drain output will go low if the battery voltage is below the low battery

threshold set at pin 3

Connect this pin to the battery and system ground

This is the regulated output voltage
