MB3775

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 high-

efficiency portable equipment.

This device contains circuitry to protect the inputs against

damage due to high static voltages or electric fields. However,

it is advised that normal precautions be taken to avoid

application of any voltage higher than maximum rated voltages

to this high impedance circuit.
