MB3785A 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.
MB3785A Key Features
- Capable of high-frequency oscillation: 100 kHz to 1 MHz
