SLUSAK8A – MAY 2011 – REVISED JUNE 2011 www.ti.com Buck PFC Controller
Check for Samples: UCC29910A FEATURES DESCRIPTION The UCC29910A 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
