PFS7625L

Overview

The PFS7625L is a Power Factor Correction (PFC) controller from the HiperPFS-4 family, designed for continuous conduction mode (CCM) operation. It integrates a high-voltage startup circuit and operates within a switching frequency range of 22 kHz to 123 kHz. The device supports a supply voltage range of 10.2 V to 15 V and functions reliably across an operating temperature range of -40°C to +125°C. Packaged in an eSIP-16G format with 16 pins and a bare thermal pad, it facilitates through-hole mounting for efficient heat dissipation.

Feature Summary

• Integrates a high-voltage startup circuit to eliminate external start-up resistors
• Supports continuous conduction mode (CCM) for high-power applications
• Features variable frequency operation to optimize efficiency across line and load conditions
• Includes comprehensive protection mechanisms such as output overvoltage and thermal shutdown

Applications

• High-power offline power supplies
• Computer and server power supplies
• Telecommunications equipment power systems
• Industrial power conversion units

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm package type and pinout compatibility. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to final design commitment. Ensure thermal management requirements align with the eSIP-16G package specifications.

Selection Notes

Select this component for designs requiring high-efficiency CCM PFC in the 150W to 400W range. Consider the integrated high-voltage startup for simplified bill of materials. Evaluate the thermal performance capabilities of the eSIP-16G package relative to the expected power dissipation and ambient operating conditions of the target application.
