Product Introduction

The PWM controller IC UC3886 series is a DC-DC converter designed for control with average current mode. It is designed for use with the UC3910 as a 4-bit DAC and voltage monitor. The UC3886 drives an external N-channel MOSFET that can be used for high-end microprocessors such as Intel Pentium\Xihang Pro.

Together with the UC3910, the UC3886 5V DC is converted to a DC system with an adjustable output range of 35mV to 100mV with accuracy from 2.0V to 3.5V.

The oscillator is the user\external resistor and capacitor x92s of choice and is designed for typical 300kHz operation.

Voltage and current amplifiers are available with a gain bandwidth of 3.5MHz to meet the requirements of high-performance systems.
