Description

The MB3785A is a PWM-based 4-channel switching regulator controller featuring high-precision, high-frequency capabilities. All of the four channels of circuits allow their outputs to be set in three modes: step-down, step-up, and inverted. The third and fourth channels are suited for DC motor speed control.

The MB3785A accepts a ceramic resonator, in addition to the standard method of oscillation using an RC network.
