6-ch DC/DC Converter IC
With Synchronous Rectification for voltage step-up and step-down
MB3827
I
DESCRIPTION
The MB3827 is a pulse width modulation (PWM) type 6-channel DC/DC converter IC with, synchronous rectifi-
cation 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.
This product is ideal for high performance portable devices such as digital still cameras.
