ASSP For Power Supply Applications (General Purpose DC/DC Converter)
2-Channel DC/DC Converter IC
with Overcurrent Protection Symmetrical-Phase Type
MB39A106
s DESCRIPTION
The MB39A106 is a symmetrical-phase type of two-channel, DC/DC converter IC using pulse width modulation (PWM) , incorporating an overcurrent protection circuit (requiring no current sense resistor) and an overvoltage protection circuit. Providing high output driving capabilities, the MB39A106 is suitable for down-conversion. The MB39A106 adopts both synchronous rectification to provide high efficiency and symmetrical phasing (two anti-phase triangular waves) which contributes to making the input capacitor small.
