Power Integrations Power Factor Correction Controller 60 kHz 16-Pin Plastic eSIP 12V PFS7728H

Power Integrations PFS7728H is a high-performance Power Factor Correction (PFC) controller operating at 60 kHz switching frequency, housed in a 16-pin plastic eSIP package. Operating at 12V supply voltage with a current capacity of 23A, this surface-mounted device is designed to optimize efficiency and power factor across varying loads and input conditions.

The PFS7728H integrates a 600 V MOSFET transistor and diode option, eliminating the need for external current sense resistors, thereby reducing power loss and simplifying design. It features innovative control techniques that dynamically adjust switching frequency based on output load, input line voltage, and input line cycle for optimal operation.

Protection features integrated into the device include undervoltage lockout (UVLO), undervoltage (UV), overvoltage (OV), overtemperature protection (OTP), brown-in/out protection, cycle-by-cycle current limiting, and power limiting to prevent overload damage. These ensure reliable and safe operation in demanding industrial and commercial applications.

Additional features include a programmable Power Good (PG) signal for system status monitoring and digital line peak detection, making it robust even under distorted input voltage conditions such as those from UPS or generator power sources. The device supports steady-state input voltages up to 305 VAC and abnormal voltages up to 410 VAC, ensuring resilience in harsh electrical environments.

The compact dimensions of 16 mm length and 1.96 mm height enable versatile usage in space-constrained PCB layouts. Its plastic eSIP surface-mount package simplifies assembly and improves thermal management, eliminating the need for insulating pads or heat spreaders.

This PFC controller is suitable for industrial applications requiring high power factor and efficiency, including power supplies, HV power management, and energy-conscious industrial equipment. It is ideal for electronics engineers and system designers working on power correction solutions in commercial and industrial electrical systems.
