1ch PFM/PWM Synchronous Rectification Step-down Regulator
MB39C001 s 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. The MB39C001 is small in size, and can achieve a DC/DC converter highly effective in the full load range, and it is the best for internal...
