UC3869A controller equivalent, high voltage green mode pwm controller.
* High voltage startup * Power on soft start reducing MOSFET VDS stress * Efficiency and minimum standby power * Frequency shuffling for EMI * Audio noise free operation .
PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range. At no load condition, .
The UTC UC3869A is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications.
