Product Overview

The PFS727EG is a high power Factor Controller with integrated high-voltage MOSFET. It provides near unity input power factor. The HiperPFS device eliminates 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. HiperPFS includes Power Integrations' standard set of comprehensive protection features, such as integrated soft-start, UV, OV, brown-in/out and hysteretic thermal shutdown. HiperPFS also provides cycle-by-cycle current limit for the power MOSFET, power limiting of the output for overload protection.
  • Accurate built-in brown-in/out protection
  • Accurate built-in undervoltage (UV) protection
  • Accurate built-in overvoltage (OV) protection
  • Hysteretic thermal shutdown (OTP)
  • Internal power limiting function for overload protection
  • Cycle-by-cycle power switch current limit
  • No external current sense required
  • Provides lossless internal sensing via sense-FET
  • Reduces component count and system losses
  • Minimizes high current gate drive loop area
  • Minimizes output overshoot and stresses during start-up
  • Integrated power limit and frequency soft start
  • Improve dynamic response
  • Input line feed-forward gain adjustment for constant loop gain across entire input voltage range
  • Provides up to 1kW peak Output power
  • High integration allows smaller form factor, higher power density designs
