For Power Supply Applications
6-ch DC/DC Converter IC
With Synchronous Rectification for voltage step-up and step-down
MB3827
s DESCRIPTION
The MB3827 is a pulse width modulation (PWM) type 6-channel DC/DC converter IC with, synchronous rectification for voltage step-up and step-down. The MB3827 is ideal for low voltage, high efficiency, compact applications and for down conversion and up/down conversion (with two types of voltage step-up/step-down methods allowing input/output relations to be set independently). In addition the MB3827 features a built-in self-supply power channel (channel 7) providing a wide range of supply voltages, and operates from two dry-cell batteries.
