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.
5,6
SW
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.

FB
Feedback Pin (FB). Through an external resistor divider
network, Feedback senses the output voltage and regulates it.
The feedback threshold voltage is 0.8V.
