产品详细介绍
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.
