P

SW (PIN1):

Switching node Output for OUT1. Connect this pin to the switching end of the inductor.

GND (PIN2):

Power Ground. It is as close to the IC as possible.

VOUT2 (PIN3):

Output voltage for OUT2. It is capable of delivering up to 300mA of output current.

Output has high impedance when disabled.

FB2 (PIN4):

Output Feedback Sense for OUT2. Receives the feedback voltage from an external

resistive divider across the output. The output voltage for OUT2 is set by a resistive divider according to

PRO (PIN5):

Power input for OUT2. Bypass to GND with a high quality ceramic capacitor placed as

close as possible to the IC.

EN (PIN6):

Enable control input for OUT1, OUT2. Drive EN to the VIN or a logic high for normal

operation, drive EN to GND or a logic low to disable OUT1, OUT2.

VIN (PIN7):

Power Input for OUT1. Bypass to GND with a high quality ceramic capacitor placed as

close as possible to the IC.

FB1 (PIN8):

Output Feedback Sense for OUT1. Receives the feedback voltage from an external

resistive divider across the output. The output voltage for OUT1 is set by a resistive divider according to
