OB2226 pin diagram and function

elecfans | 29/04/2021

OB2226 is a high-performance, high-precision PWM controller with built-in error amplifier, load compensation, fixed frequency oscillator, soft start, circulating current limit, overload protection, output short circuit protection, over temperature protection and VDD undervoltage protection And other functions. OB2226 is widely used in low-power AC/DC offline switching power supplies, such as induction cookers, LCD power supplies and other equipment. The OB2226 series has two packaging processes, one is that OB2226SP uses a 7-pin DIP package, and the other is that OB2226CP and OB2226AP use an 8-pin SOP package.

OB2226 pin function

1, INV error amplifier's inverting input.

2, the output pin of the COMP error amplifier. A feedback compensation network is connected between this pin and INV pin.

3, MULT multiplier input pin. The full AC voltage is allocated 2V to the MULT pin.

4, CSPWM comparator input pin. After the MOSFET tube current passes through a resistor, it is converted into a voltage and supplied to the CS pin. The built-in R/C filter can suppress any high frequency noise.

5, ZCD zero current detection input pin.

6, GND ground pin.

7, OUT threshold driver output pin. Drive the power MOSFET tube.

8. The working voltage of VCC driver and control circuit.
