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.

5

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.

8

LBO

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
