Power Integrations Power Factor Correction Controller Plastic eSIP 12V 60 kHz 16-Pin PFS7724H

Power Integrations PFS7724H is a high-performance Power Factor Correction (PFC) controller IC designed for industrial and electronic power management applications. It operates with a switching frequency of 60 kHz and is housed in a 16-pin Plastic eSIP package configured for surface mount technology.

This controller optimizes power factor and efficiency across a wide range of load conditions. The integrated design includes a 600 V MOSFET and diode options, eliminating the need for external current sense resistors and reducing power loss.

It supports a supply current of 23A with operating voltage from 5V minimum up to 12V maximum, making it versatile for various power supply and power quality control systems. The robust device functions reliably in a wide temperature range from -40°C to 150°C, suitable for demanding environments.

Protection features embedded in the PFS7724H include undervoltage lockout (UVLO), over-voltage protection (OV), over-temperature protection (OTP), brown-in/out detection, cycle-by-cycle current limiting, and power limiting for overloads. These ensure safe and continuous operation in industrial and commercial power factor correction circuits.

Additional intelligent control features include a programmable Power Good signal, digital line peak detection to handle distorted input voltages from UPS or generators, and a digital power factor enhancer to compensate for EMI filter and bridge distortions. Spread-spectrum operation above 60 kHz window simplifies EMI filtering requirements.

The compact dimension of 16 mm length by 1.96 mm height in a plastic eSIP package allows space-efficient PCB designs, beneficial for modern, high-density electronic modules.

Applications include industrial power supplies, renewable energy inverters, UPS systems, and other electronic power management systems where high power factor and efficiency are critical.
