The MB3788 is a dual-channel PWM-type switching regulator controller; it incorporates a reference voltage.
The MB3788 has a PWM circuit and an output circuit as well as a reference voltage power supply with a voltage accuracy of ±1%. The maximum operating frequency is 1 MHz. It is designed for a voltage-drop output switching regulator suitable for a logic power supply or speed control of a DC motor.
The MB3788 is compatible with all master ICs producing triangular waves, sawtooth waves and sine waves with an amplitude of 1.3 to 1.9 V. It can be used in high-performance portable equipment such as a video camcorder or notebook personal computer (word processor).
