LOW VOLTAGE DUAL PWM SWITCHING
REGULATOR CONTROLLER
The MB3775 is a dual pulse-width-modulation control circuit.
It contains the basic circuits required for two PWM control circuits.
Complete synchronization is obtained by using the same oscillator output waveform.
This IC can provide following types of output voltage: step down, step up, and inverter.
Power consumption is low, thus the MB3775 is ideal for use in highefficiency portable equipment.
