Table 1 Pin Description
Pin Number Pin Name Description
1
EN
Enable Pin. Drive EN pin low to turn off the device, drive it
high to turn it on. Floating is default high.
2
VIN
Supply Voltage Input Pin. HM6281 operates from a 3.6V to 24V
DC voltage. Bypass Vin to GND with a suitably large capacitor
to eliminate noise on the input.
3
FB
Feedback Pin (FB). The feedback threshold voltage is 0.22V.
4
NC
No Connected.
5,6
SW
Power Switch Output Pin (SW). Output is the switch node that
supplies power to the output.
7,8
GND
Ground Pin.
