PFS7533H

Overview

The PFS7533H is a power factor correction controller from the HiperPFS-3 family, designed for continuous conduction mode (CCM) boost PFC applications. It supports a peak power of 280 W with an input voltage range of 180 VAC. The device integrates a high-voltage startup circuit and operates within a temperature range of -40°C to 150°C. Packaged in an eSIP-16D format, it combines PFC control with primary-side regulation capabilities for efficient offline AC/DC conversion.

Feature Summary

• Integrates CCM boost PFC controller with primary-side regulation
• Includes high-voltage startup circuit eliminating external bias winding
• Provides comprehensive protection against overvoltage, undervoltage, and thermal faults

Applications

• Offline AC/DC power supplies
• Battery chargers
• Consumer electronics adapters

Procurement Notes

Verify the specific suffix 'H' corresponds to the required package variant and compliance status. Confirm that the 180 VAC input specification aligns with your system design requirements. Ensure compatibility with the eSIP-16D footprint during PCB layout. Check current availability status as supply chain conditions may vary.

Selection Notes

Select this component for designs requiring integrated PFC and regulation in a compact form factor. It is suitable for applications needing high efficiency and reduced component count. Consider the 280 W peak power limit when sizing the transformer and passive components. Evaluate thermal management needs given the wide operating temperature range.

Part Context

This part belongs to the HiperPFS-3 series, which merges power factor correction and DC-DC conversion into a single IC. The series targets high-efficiency offline power supplies. The PFS7533H specifically addresses mid-power applications requiring robust protection features and simplified bill of materials compared to discrete solutions.

Replacement Considerations

Consider the PFS7535H or PFS7536H for higher power requirements within the same family. Verify pinout and electrical parameter compatibility before substitution. Review datasheet updates for any changes in recommended operating conditions.
