8 Detailed Description

8.1 Overview

The UCC28180 is a boost controller for power factor correction operating at a fixed frequency in continuous

conduction mode. The UCC28180 requires few external components to operate as an active PFC pre-regulator.

UCC28180 employs two control loops. An internal error amplifier and 5-V reference provide a slow outer loop to

control output voltage. External compensation of this outer loop is applied by means of the VCOMP pin. The

inner current loop shapes the average input current to match the sinusoidal input voltage. The inner current loop

avoids the need to sense input voltage by exploiting the relationship between input voltage and boost duty-cycle.

External compensation of the inner current loop is applied by means of the ICOMP pin.

The operating switching frequency can be programmed from 18 kHz to 250 kHz simply by connecting the FREQ

pin to ground through a resistor.

UCC28180 includes a number of protection functions designed to ensure it is reliable, and will provide safe

operation under all conditions, including abnormal or fault conditions.
