Description

1

LBI

Battery low voltage detector input. The internal threshold is set to 0.6V. The external threshold

can be adjusted by using an external resistor divider.

2

COMP

Error amplifier output. Compensate it with a 220pF capacitor

3

VFB

Error amplifier input. The output voltage can be adjusted by using an external resistor divider

4

GND

Ground.

LX

Switch node connection to the inductor.

6

VCC

Input voltage.

7

SYNC

This pin allows to select Low Noise/ Low Consumption Mode or to sychronize the device.

8LBO

Battery low voltage detector output. If the voltage at the LBI pin drops below the internal

thrshold, LBO goes low. The LBO is an open drain output. A pull_up resistor should be

connected between the pin and the output voltage
