The Integrated Circuit OB2269AP is a highly integrated current mode operational PWM “Pulse Width Modulator” control IC chip. It is optimised for the high performance and low standby power cost effective field effect transistor. It shows flyback converter above 20W power level. Externally triggered and trimmed PWM Switching frequency is at the normal operation at no load and light condition. The burst mode is for minimizing the switching loss of the electronic circuit. By this method lower standby power and higher conversion efficiency is easily achieved.
VDD low start-up and current operating on reliable power design is fabricated. To minimise the the standby power of the IC high value resistor is used. The leading-edge large signal stability and blanking glitch circuit diode is the reverse recovery. Cycle-by-cycle current limiting (OCP), Over temperature protection (OTP), Over Voltage protection (OVP) etc. are provided with complete protection and self-recovery. The tone energy of the Integrated Circuit below 20 KHZ is minimised in the circuitry operation. And with this method audio noise performance is also greatly improved.
OB2269AP Key Features:
1. The IC has extended burst mode control for improving standby efficiency
2. Programmable switching PWM frequency
3. It is internal synchronised slope compensation
4. Low Vin/Vdd 4uA
5. Maximum gate voltage clamp is 18V
6. Shows leading edge and current sense input
7. Complete protection and auto self-recovery
8. Audio frequency noise operation
9. Frequency technology and shuffling operation
