PFS7526H [Power Integrations]

The HiperPFS-3 devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver, ultra-low reverse recovery (Qspeed) diode and high-voltage power MOSFET in a single package. They eliminate external current sense resistors and use an innovative control technique that adjusts switching frequency over output load, input line voltage, and input line cycle. This maximizes efficiency across the entire load range, particularly at light loads, and minimizes EMI filtering requirements. The devices are suitable for PFC applications from 75 W to 900 W.
