Description
The HiperPFS-2 device family members reach a very high level of integration including a continuous conduction mode (CCM) boost PFC controller, gate driver, ultra-low reverse recovery (Qspeed) diode (eeSIP™ package options) and high-voltage power MOSFET in a single, low-profile CoolPAD (GROUND pin connected) power package that is able to provide near unity input power factor. The HiperPFS-2 devices eliminate the PFC converter’s need for external current sense resistors, the power loss associated with those components, and leverages an innovative control technique that adjusts the switching frequency over output load, input line voltage, and even input line cycle.
