Description
The XY6112P is a high-performance offline PFM+PWM switching power controller with an integrated high-voltage power MOSFET, designed for AC/DC conversion in compact power supplies, typically packaged in DIP-8. It supports wide input voltage operation (AC85–300V), low standby power, adaptive frequency control, and multiple protection features including OVP, OTP, and overload protection. This controller is widely used in chargers, adapters, and standby power supplies for consumer electronics and industrial applications.
Features
- Integrated high-voltage power MOSFET for simplified design
- Wide AC input range (85V to 300V)
- PFM + PWM hybrid control for high efficiency
- Low standby power consumption (<0.15W)
- Built-in startup circuit reducing external resistor loss
- Output power up to 15W (continuous), 18W (peak)
- Over-voltage protection (OVP) and over-temperature protection (OTP)
- Overload, short-circuit, and transformer saturation protection
- Input voltage compensation for constant power output
- Minimal external components for low system cost
