ME3101 同步DC-DC降压转换器IC 笔记本电脑数码相机芯片

me3101 series
500ma synchronous step-down dc/dc converters

description：
      me3101 series is a group of synchronous rectification type dc/dc converters with a built-in 0.6p-channel driver transistor and 0.7n-channel switching transistor, designed to allow the use of ceramic capacitors. the ics enable a high efficiency, stable power supply with an output current of 500ma to be configured using only a coil and two capacitors connected externally. with the built-in oscillator, oscillation frequency is 1.2mhz.as for operation mode, the me3101 series can be manually switched with automatic pwm/pfm switching control mode, allowing fast response, low ripple and high efficiency over the full range of load (from light load to high output current conditions). during standby, all circuits are shutdown to reduce current consumption to as low as 1.0μa or less.
