Low Standby-Power Off-line PWM converters
Product：PN8124F
1、Product application

2、General Description
The PN8124F consists of an integrated Pulse Width Modulator (PWM) controller and power MOSFET， specifically designed forsmall power non-isolated switching power supply. PN8124F offers fully intelligentized protection including Cycle-by-Cycle currentlimiting (OCP); Over Voltage Protection (OVP), Over Load Protection (OLP), Under Voltage Lockout and Over TemperatureProtection (OTP). Excellent EMI performance is achieved with Pulse Frequency Modulation. PN8124F also consists of the highvoltage start-up circuit to ensure that start quickly. The application need less component device.
