UCC28051D. - PFC Controller IC, 12 V to 18 V & 4 mA supply

Descrição geral do produto

The UCC28051D is a transition mode Power Factor Correction (PFC) Controller for low-to-medium power applications requiring compliance with IEC 1000-3-2 harmonic reduction standard. It is designed for a boost preregulator operating in transition mode (also referred to as boundary-conduction mode or critical conduction-mode operation). It features a transconductance voltage amplifier for feedback error processing, a simple multiplier for generating a current command proportional to the input voltage, a current-sense (PWM) comparator, PWM logic and a totem-pole driver for driving an external FET. In the transition mode operation, the PWM circuit is self-oscillating, with the turn-on being governed by an inductor zero-current detector (ZCD pin) and the turnoff being governed by the current-sense comparator. Additionally, the controller provides features such as peak current limit, default timer, overvoltage protection (OVP) and enable.
