PFS7725H

Overview

The PFS7725H is a HiperPFS-4 integrated power factor correction controller featuring a built-in 600 V power MOSFET. Designed for through-hole installation in an eSIP-16G package, it operates with a fixed switching frequency of 60 kHz. The device supports a wide input voltage range from 90 V AC to 265 V AC and delivers a maximum output voltage of 530 V. It is rated for continuous output power up to 90 W at 230 V AC. The component functions within an operating temperature range of -40 °C to +150 °C.

Feature Summary

• Integrates a 600 V power MOSFET with a CCM boost PFC controller and gate driver in a single low-profile package.
• 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 via spread spectrum effects.
• Incorporates advanced digital line monitoring and analog core control to maintain extremely low no-load power consumption.

Applications

• High-efficiency power factor correction stages in compact AC/DC power supplies
• Power adapters for consumer electronics and IT equipment
• Industrial power supply designs requiring high reliability and low standby power
