PFS7723H

Overview

The PFS7723H is a HiperPFS-4 family power factor correction controller integrating a continuous conduction mode (CCM) boost PFC controller, gate driver, and 600 V power MOSFET. It operates at a fixed switching frequency of 60 kHz with a supply voltage range of 5 V to 12 V. The device utilizes an eSIP-16D package with dimensions of 16 mm length and 1.96 mm height. It supports an operating temperature range from -40 °C to +150 °C TJ.

Feature Summary

• Eliminates external current sense resistors by using innovative control techniques that adjust switching frequency over output load, input line voltage, and input line cycle.
• Minimizes EMI filtering requirements through wide bandwidth spread spectrum effects inherent in the control technique.
• Features advanced digital techniques for line monitoring, line feed-forward scaling, and power factor enhancement alongside analog core controller for low no-load consumption.

Applications

• High-efficiency power factor correction stages
• Applications requiring minimized EMI filtering
• Light load efficiency optimization scenarios

Procurement Notes

Verify the specific suffix 'H' indicates the correct eSIP-16D package variant. Confirm the 60 kHz fixed frequency requirement matches the design specifications. Ensure the 600 V MOSFET rating aligns with the target boost converter topology. Validate the 5 V to 12 V supply voltage compatibility with the system's auxiliary power rail.

Selection Notes

Select this component when a fixed 60 kHz switching frequency is required rather than variable frequency operation. Choose the eSIP-16D package for low-profile surface mount integration. Consider the integrated 600 V MOSFET for simplified bill of materials compared to discrete solutions. Verify thermal management capabilities for the -40 °C to +150 °C operating range.

Part Context

The PFS7723H belongs to the HiperPFS-4 family, which integrates CCM boost PFC controllers with power MOSFETs. This family emphasizes high efficiency across load ranges and reduced EMI through spread spectrum techniques. It replaces previous generations like HiperPFS-3 by offering enhanced digital control features and lower no-load power consumption.

Replacement Considerations

Public confirmed substitutes include PFS7725H within the same HiperPFS-4 family. Verify pinout and electrical parameter compatibility before substitution. Check datasheet revisions for any functional differences between variants.
