Power Integrations HiperPFS, HiperTFS Controllers

HiperPFS™ Family High Power PFC Controllers

Power Integrations HiperPFS™ Family High Power PFC Controllers each incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver, and high-voltage power MOSFET in a single, low-profile eSIP™ power packagethat is able to provide near unity input power factor. These controllers eliminate the PFC converter's need for external current sense resistors and the power loss associated with those components, and leverage 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, and also significantly minimizes the EMI filtering requirements due to its wide-bandwidth spread spectrum effect. Power Integrations HiperPFS™ Family HighPower PFC Controllers include Power Integrations' standard set of comprehensive protection features, such as integrated soft-start, UV, OV, brown-in/out, and hysteretic thermal shutdown. They also provide cycle-by-cycle current limit for the power MOSFET, power limiting of the output for overload protection, and pin-to-pin short-circuit protection.

HiperPFS™ & HiperTFS™ Controllers

Power Integrations HiperPFS™ and HiperTFS™ Controllers each come with high-voltage power MOSFETs and are housed in a single, low-profile eSIP™ power package. Both the HiperPFS & HiperTFS series include Power Integrations' standard set of comprehensive protection features, such as integrated soft-start and hysteretic thermal shutdown.
