FEATURES

DESCRIPTION

•

Buck Power Factor Correction for High

Efficiency Across Line

The UCC29910 Buck Power Factor Correction (PFC)

controller provides a relatively flat high-efficiency

performance across universal line for designers

requiring a high power factor (>0.9) and wishing to

meet the requirements of IEC 61000-3-2. Based on a

Buck Topology, inherent inrush current limiting

eliminates the need for additional components. With a

typical bus voltage of 84 V, the topology is ideally

suited for use with low voltage stress downstream

regulation/isolation power trains, such as half-bridge

stages controlled by the UCC29900, (Texas

Instruments Literature Number, SLUS923). This

combination offers low common mode noise

Low Off-Line Startup Current, With SmartStart

Algorithm for Fast Startup With Soft-Start

Compatible With Resistive or Pass Transistor

Fed Startup from the AC Line

Low Power SmartBurst Mode for Standby and

Light-Load Conditions

Current Sense Inputs for PFC control and

Overload Protection

exceptionally high conversion efficiency.

•

Latching Fault Input Pin

The UCC29910 is a highly integrated controller

designed for ease of use, which incorporates all the

control features needed for high efficiency designs. It

incorporates AC mains UVLO and controlled soft start

for fast start-up and with “no spark” will not require

the use of additional inrush protection circuitry. A

particular design goal of the part is enhanced

light-load efficiency, achieved through advanced

management algorithms for best-in-class no-load and

light-load performance.
