1-channel DC/DC Converter IC

with Synchronous Rectifier

MB3885

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.

FEATURES

• Synchronous rectification for high efficiency

• Supply voltage range : 5.5 V to 18 V

• Built-in high-precision reference voltage circuit : 2.5 V

• Error Amp. threshold voltage : 1.25 V

• Oscillator frequency range : 10 kHz to 500 kHz

• Built-in soft start circuit with error Amp. input control

• Totem pole type output for N-ch MOSFET
