Power Integrations HiperPFS-2
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. This control technique is designed to maximize efficiency over the entire load range of the converter, particularly at light loads. The HiperPFS-2 also features an integrated non-linear amplifier for enhanced load transient response, a user programmable power good (PG) signal as well as user selectable power limit functionality.
