PFS7633H [Power Integrations]

The HiperPFS-4 devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver and 600 V power MOSFET in a single, low-profile power 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, minimizes EMI filtering requirements through spread-spectrum effects, and reduces component count while enhancing reliability compared to discrete solutions.
