MB3883 Description

The MB3883 is a 6-channel step-up/step-down DC/DC converter IC using pulse width modulation (PWM) and synchronous rectification, designed for low voltage, high efficiency, and pact size. This IC is ideal for up conversion, down conversion, and up/down conversion (using a step-up/step-down Zeta system with free input and output settings). The MB3883 can operate at low voltage levels, and has a wide supply voltage...
