NAME

DESCRIPTION

1

FB

Feedback Input. Connect a resistive voltage divider from the output voltage to FB to set the

output voltage. The feedback regulation threshold is 1.23V.

2

GND

Ground

3

SW

High side of the Switch transistor. The Low side of the Switch transistor is internally

connected to GND

4

VCC

Internal Power Input. VCC powers the internal circuitry. If the input source remains above

3.0V, VCC can be connected to the input source to reduce power consumption.

5

EN

Enable. A high voltage at EN turns on the converter, and a low voltage turns it off. When

not used, connect EN to the input source for automatic startup. If EN is driven over 6V,

place a 10 kΩ to 47kΩ resistor in series with EN.

3.3V to 5.0V application
