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 compact 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 range from 1.7 V to 9 V.

The MB3883 is available in two packages, an LQFP-48P or a leadless BCC-48P formed with a contact electrode pad only.

MB3883 is an ideal power supply for high-performance portable devices such as digital still cameras.
