UC3869 - HIGH VOLTAGE GREEN MODE PWM CONTROLLER

UC3869 Description

UNISONIC TECHNOLOGIES CO., LTD UC3869 Preliminary HIGH VOLTAGE GREEN MODE PWM CONTROLLER * .
The UTC UC3869 is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consum.

UC3869 Features

* High voltage startup
* Power on soft start reducing MOSFET Vds stress
* Efficiency and minimum standby power
* Frequency shuffling for EMI
* Audio noise free operation
* Fixed 65KHZ switching frequency
* Comprehensive protection coverage VDD Under Voltage Lockout with H

UC3869 Applications

* PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range. At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition. The internal slope compensation improve
