PFS7623L

Overview

The PFS7623L is a HiperPFS-4 family power factor correction controller featuring an integrated 600 V power MOSFET and gate driver in a low-profile InSOP-24B package. It operates in continuous conduction mode (CCM) with a switching frequency range of 22 kHz to 123 kHz. The device supports input voltages from 90 VAC to 264 VAC and delivers up to 75 W of output power. Key electrical parameters include a supply voltage range of 10.2 V to 15 V, a maximum operating junction temperature of 150 °C, and a minimum operating temperature of -40 °C.

Feature Summary

• Eliminates external current sense resistors by utilizing innovative control techniques that adjust switching frequency based on load and line conditions.
• Maximizes efficiency across the entire load range, particularly at light loads, while minimizing EMI filtering requirements through spread spectrum effects.
• Integrates advanced digital techniques for line monitoring and power factor enhancement alongside analog core control for extremely low no-load consumption.

Applications

• High-efficiency power factor correction stages for consumer electronics
• Power supplies for personal computers and printers
• LCD television power architectures
• Video game console power systems
