UC3886 Datasheet (Unitrode) - Average Current Mode PWM Controller

UC3886, Average Current Mode PWM Controller

The UC3886 family of PWM controller ICs is designed for DC-to-DC converters with average current mode control.

It is designed for use in conjunction with the UC3910 4-bit DAC and Voltage Monitor.

The UC3886 drives an external N-channel MOSFET and can be used to power the Intel Pentium® Pro and other
