No Connected.

VIN

Supply Voltage Input Pin. HM1513 operates from a 3.6V to 18V

DC voltage. Bypass Vin to GND with a suitably large capacitor

to eliminate noise on the input.

Power Switch Output Pin (SW). Output is the switch node that

7,8

GND

Ground Pin. Care must be taken in layout. This pin should be

placed outside of the Schottky Diode to output capacitor ground

noise into HM1513.

Feedback Pin (FB). Through an external resistor divider

network, Feedback senses the output voltage and regulates it.

The feedback threshold voltage is 0.8V.

Enable Pin. Drive EN pin low to turn off the device, drive it
