Power Integrations PFS7728H, PFC Controller, 60 kHz, 12 V 16-Pin, Plastic eSIP

The Power Integrations e HiperPFS-4 family PFC controller has Integrated 600 V MOSFET T and diode option in a single, low-profile power package. It is optimized for high PF and efficiency across load range. HiperPFS-4 devices eliminate need for external current sense resistors and their associated power loss, and use an innovative control technique that adjusts the switching frequency over output load, input line voltage, and input line cycle.

Programmable Power Good (PG) signal
Digital line peak detection for robust performance even with
distorted input voltage from UPS or generators
Digital power factor enhancer compensates for EMI filter and bridge distortion
Spread-spectrum across >60 kHz window simplifies EMI filtering
Protection features include: UVLO, UV, OV, OTP, brown-in/out, cycleby-cycle current limit and power limiting for overload protection
Withstands 305 VAC steady-state and 410 VAC abnormal input
Eliminates insulating pad/heat-spreader
