DC/DC Converter IC with Synchronous
Rectifier
for Voltage Step-up and Step-down
MB3883
I
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.
This is an ideal power supply for high-performance portable devices such as digital still cameras.
