PFS7624L [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. It eliminates external current sense resistors and uses an innovative control technique that adjusts switching frequency over output load, input line voltage, and input line cycle. This maximizes efficiency over the entire load range, particularly at light loads, and minimizes EMI filtering requirements due to wide bandwidth spread spectrum effect. It features integrated non-linear error amplifier for enhanced load transient response, user programmable Power Good (PG) signal, and user selectable power limit functionality. It includes comprehensive protection features such as UV, OV, brown-in/out, hysteretic thermal shutdown, cycle-by-cycle current limit, and power limiting for overload protection.
