HT2269, Current Mode PWM Controller

HT2269 Current Mode PWM Controller GENERAL .
HT2269 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback convert.

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(6.5uA) and Low Operating Current (2.3mA)

Applications

* PWM switching frequency at normal operation is frequency shuffling technique together with soft switching control at the totem pole gate drive output. The tone energy at below 20KHZ is minimized in operation. Consequently, audio noise erformance is greatly improved. HT2269 is offered in both SOP8
