Description: Current Mode PWM Controller

Features

* Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
* Audio Noise Free Operation
* External Programmable PWM Switching Frequency
* Internal Synchronized Slope Compensation
* Low VIN/VDD Startup Current(4uA) and Low Operating Current (2.3mA)

Applications

* in above 20W power level. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved.
