PFS7534H

Overview

The PFS7534H is a HiperPFS-3 family power factor correction controller designed for continuous conduction mode (CCM) applications. It supports a peak output power of 350 W with an input voltage range of 180 VAC. The device operates within a switching frequency range of 22 kHz to 123 kHz and utilizes a 16-pin eSIP-16D package. It features a supply voltage range of 10.2 V to 15 V and functions reliably across an operating temperature range from -40°C to 150°C.

Feature Summary

• Integrates CCM PFC control with digital input voltage peak detection for reliable performance under distorted voltage conditions
• Includes built-in protection mechanisms such as output undervoltage, overtemperature, input overvoltage, and output short circuit
• Features internal X-capacitor discharge and high-voltage self-supply during startup to simplify design

Applications

• Power supplies for personal computers and printers
• LCD television power stages
• Video game consoles
• High-power adapters and USB PD fast chargers
• Industrial control systems and home appliances

Procurement Notes

Verify the specific suffix 'H' indicates the correct package variant and lead-free status. Confirm RoHS compliance details against the latest manufacturer datasheet. Ensure the ordering quantity matches the standard tube packaging requirements specified by Power Integrations for this component series.

Selection Notes

Select this component for designs requiring up to 350 W peak power in CCM topology. It is suitable for universal input ranges starting at 180 VAC. Consider the thermal characteristics of the eSIP-16D package for heat dissipation planning. Verify compatibility with downstream LLC or flyback controllers if used in complete power supply architectures.

Part Context

This part belongs to the HiperPFS-3 family, which combines PFC and DC/DC control capabilities. It is designed to reduce component count and system size compared to discrete solutions. The family targets high-efficiency applications requiring strict power factor correction standards without external heat sinks in many configurations.

Replacement Considerations

Check the HiperPFS-3 family datasheet for pin-compatible alternatives like PFS7533H or PFS7535H based on required power levels. Verify that any substitute maintains the same eSIP-16D package and electrical specifications.
