Information

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 (eSIP 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. This control technique is designed to maximize efficiency over the entire load range of the converter, particularly at light loads. Additionally, this control technique significantly minimizes the EMI filtering requirements due to its wide bandwidth spread spectrum effect. 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. HiperPFS-2 includes Power Integrations’ standard set of comprehensive protection features, such as integrated soft-start, UV, OV, brown-in/out, and hysteretic thermal shutdown. HiperPFS-2 also provides 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-2’s innovative variable frequency continuous conduction mode of operation (VF-CCM) minimizes switching losses by maintaining a low average switching frequency, while also varying the switching frequency in order to suppress EMI, the traditional challenge with continuous conduction mode solutions.
