Power Integrations HiperPFS-4 PFC Controller

HiperPFS-4 PFC controller

HiperPFS™-4 devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver and 600 V power MOSFET in a single low-profile (GROUND pin connected) power package. HiperPFS-4 devices eliminate the need for external current sense resistors, also eliminating their associated power loss, and instead use an innovative control technique that adjusts the switching frequency over output load, input line voltage, and input line cycle.

This control technique maximises efficiency over the entire load range, particularly at light loads. Additionally, it minimises the EMI filtering requirements due to its wide bandwidth spread spectrum effect. HiperPFS-4 uses advanced digital techniques for line monitoring, line feed-forward scaling, and power factor enhancement; while using analog techniques for the core controller in order to maintain extremely low no-load power consumption.

HiperPFS-4 also features an integrated non-linear error amplifier for enhanced load transient response, a user programmable Power Good (PG) signal as well as user selectable power limit functionality. HiperPFS-4 includes Power Integrations’ standard set of comprehensive protection features, such as UV, OV, brown-in/out, and hysteretic thermal shutdown. HiperPFS-4 also provides cycle-by-cycle current limit and Safe Operating Area (SOA) protection of the power MOSFET, output power limiting for overload protection, and pin-to-pin short-circuit protection.
