DC-DC Step Down Buck Converter XH-M401

DC-DC Step Down Buck Converter XH-M401 Power Supply Module is a 180 kHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 12A load with high efficiency, low ripple, and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.

The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over-current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.

Features:

• Wide 8V to 36V Input Voltage Range
• Output Adjustable from 1.25V to 32V
• High efficiency up to 96%
• Built-in thermal shutdown function
• Built-in current limit function
• Built-in output short protection function
• Excellent line and load regulation

Applications:

• LCD Monitor and LCD TV
• Portable instrument power supply
• Telecom / Networking Equipment

Package Includes:

• 1 x DC-DC Step-Down Buck Converter XH-M401
