MB39C001 Description
The MB39C001 is a synchronous rectification type of single-channel, step-down DC/DC converter IC using current mode control. The MB39C001 integrates switching FETs, an oscillator, error amplifier, voltage detector, and a reference voltage generator in a 18-pin BCC package. The required external ponents are only a coil and decoupling capacitors.
