CRE2269 - Current Mode PWM Power Switch

Ground Feedback input pin.

PWM duty cycle is determined by voltage level into this pin and current-sense signal level at Pin 6.

Connected through a large value resistor to rectified line input for Start upchip supply and line voltage sensing.

Internal Oscillator frequency setting pin.

CRE2269 Current Mode PWM Power Switch CRE2269 is a highly intergrated current mode PWM control IC for high performance, low standby power and cost effective offline flyback converter applications in abive 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”birst mode”ti minimize switching loss.Lower standby power and higher conversion efficiency is thus achieved.
