GENERAL DESCRIPTION
ME3101 series is a group of synchronous rectification type DC/DC converters with a built-in 0.6Ω P-channel driver transistor and 0.7Ω N-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, During standby, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less.
