WIS2269N8 Description
WIS2269 is a highly integrated, high performance current mode PWM controller chip. Apply to the power adapter and other small and medium-power switch power supply. In order to reduce standby power consumption to meet the higher standards of environmental protection, the chip provides a pulse mode (Burst Mode) function, very low starting current and operating current.

- Built-edge blanking
- Built-in synchronized slope pensation
- Current mode
- External Programmable PWM Switching Frequency
- By-cycle current limit protection (OCP)
- VDD over-voltage clamping protection
- Low voltage shut down function (UVLO)
