HiperPFS�-4 PFC controller with integrated 600V MOSFET and diode option are optimized for high PF and efficiency across load range. Devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver and 600V power MOSFET in a single low-profile (GROUND pin connected) power package. HiperPFS-4 devices eliminate need for external current sense resistors, also eliminating their associated power loss and instead use an innovative control technique that adjusts the switching frequency over output load, input line voltage and input line cycle. HiperPFS-4 uses advanced digital techniques for line monitoring, line feed-forward scaling and power factor enhancement, while using analogue techniques for the core controller in order to maintain extremely low no-load power consumption. Applications includes PC, high-power adaptors, printer, high-power LED lighting, LCD TV, industrial and appliance, video game consoles, generic PFC converter and 80 Plus� platinum designs.
- Universal input devices with integrated diode, 385W peak output power (full power mode)
- >95% efficiency from 10% load to 100% load, <60mW no-load consumption at 230VAC
- Integrated non-linear error amplifier for enhanced load transient response
- User programmable power good (PG) signal and user selectable power limit functionality
- Digital line peak detection for robust performance with distorted I/P voltage from UPS/generators
- Digital power factor enhancer compensates for EMI filter and bridge distortion
- Spread-spectrum across >60KHz window simplifies EMI filtering
- UVLO, UV, OV, OTP, brown-in/out, cycle by-cycle current limit, power limiting
- Withstands 305VAC steady-state and 410VAC abnormal input, eliminates insulating pad/heat-spreader
- Minimizes EMI filtering requirements due to its wide bandwidth spread spectrum effect
