PFS7726H

Overview

The PFS7726H is a HiperPFS-4 family power factor correction controller integrating a CCM boost PFC controller, gate driver, and 600 V power MOSFET in an eSIP-16D package. It operates with a switching frequency range of 22 kHz to 123 kHz and requires a supply voltage of 10.2 V to 15 V. The device supports through-hole mounting and functions within a junction temperature range of -40°C to 150°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 analog techniques for core control to maintain extremely low no-load power consumption.

Applications

• High-efficiency AC-DC power supplies
• Offline power converters requiring continuous conduction mode
• Applications demanding low no-load power consumption
