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

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
