DESCRIPTION
The MB3885 is a 1-channel DC/DC converter IC using pulse width modulation (PWM) and synchronous rectifi-
cation, designed for down conversion applications.
This device is a power supply with high output drive capacity. Synchronous rectification also provides for high
efficiency.
In addition, a 5 V regulator is built in to reduce the number of system components. The result is an ideal built-in
power supply for driving products with high speed CPU’s such as home TV game devices and notebook PC’s.
