HM3105 Datasheet Buck DC-to-dc Converter

Manufacturer: H&M Semiconductor

Overview: 5A 180KHz 36V Buck DC to DC Converter.

General Description

The HM3105 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.

Requiring a minimum number of external ponents, the regulator is simple to use and include internal frequency pensation and a fixed-frequency oscillator.

The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.
