45V Input Buck Converter 3ch/2ch IC with Power MOSFET_{Ｑｕaｌｉｔｙ is our message}

Features

FA7726/7730

1. Wide Input Voltage Range : 10 to 45V

2. 75 to 85% High Efficiency is achieved by

using internal power MOSFETs with

synchronized rectifier.

3. Low Operating Current : 3.5mA

4. Protection : Current Limit of power MOSFET,

Each channel soft start, Timer Latched

Protection for Short Current and Over

Temperature
