Description: HIGH VOLTAGE GREEN MODE PWM CONTROLLER

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 100KHZ switching frequency
* Comprehensive protection coverage VDD Under Voltage Lockout with

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
