ME3148
ME3148 is 160KHz Buck DC/DC Converter manufactured by ChipSourceTek.
Description
Features
The ME3148 is a 160KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving
- Input Voltage Range 8V~36V
- Maximum output current 3A a 3A load with high efficiency, low ripple and excellent
- Fixed 160KHz Switching Frequency line and load regulation. Requiring a minimum
- Output Adjustable from 1.25V to 33V number of external ponents, the regulator is simple to use and include internal frequency
技 pensation and a fixed-frequency oscillator. k The PWM control circuit is able to adjust the duty 科 e ratio linearly from 0 to 100%. An enable function, an T over current protection function is built inside. An 特 e internal pensation block is built in to minimize 源 rc external ponent count.。
