Product Description

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.
Industry pin compatibility with improved feature set
Improved transient response with slew-rate comparator
Accurate internal VREF for tight output regulation
OVP, open-feedback protection and enable circuits
±750mA Peak gate drive current
Low startup and operating current
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
