DESCRIPTION

Product Summary

The HM3134 series is a monolithic control

circuit delivering the main functions for DC-DC

voltage converting.

20~ 200V

The device contains an internal temperature

compensated reference, comparator, duty cycle

controlled oscillator with an active current limit

circuit, driver and high current output switch.

Output voltage is fixed 15V ,integrated two external

resistors with a 2% reference accuracy.
