Frequently Asked Questions

What is the input voltage range of the UC2852N?

The UC2852N operates with a supply voltage from 12.5V (minimum) to 30V (maximum), with a nominal supply of 24V, making it suitable for typical boost PFC preregulator designs powered from rectified mains.

What control method does the UC2852N use for power factor correction?

The UC2852N uses current-mode pulse-width modulation (PWM) control to shape the input current waveform to follow the sinusoidal AC input voltage, achieving high power factor and reducing harmonic distortion in the AC line current.

What package does the UC2852N come in, and is it RoHS compliant?

The UC2852N is available in a standard 8-pin Dual-In-Line (DIP-8) through-hole package (JESD-30 code R-PDIP-T8). It is RoHS compliant with a Pb-free designation (JESD-609 code e4), meeting environmental regulations for lead-free manufacturing.

What are typical applications for the UC2852N?

Typical applications include boost power factor correction preregulators for AC-DC power supplies in computers, telecom equipment, industrial drives, and UPS systems, where IEC 61000-3-2 compliance for harmonic current limits is required.

Are there modern replacements or alternatives for the UC2852N?

Texas Instruments offers more modern PFC controllers such as the UCC28180 and UCC28019A that provide enhanced features including transition-mode and continuous-conduction-mode PFC control with integrated protections, which may be considered as alternatives for new designs.
