3 Description
The UCC28180 is a flexible and easy-to-use, 8-pin,
active Power-Factor Correction (PFC) controller that
operates under Continuous Conduction Mode (CCM)
to achieve high Power Factor, low current distortion
and excellent voltage regulation of boost pre-
regulators in AC - DC front-ends. The controller is
suitable for universal AC input systems operating in
100-W to few-kW range with the switching frequency
programmable between 18 kHz to 250 kHz, to
conveniently support both power MOSFET and IGBT
switches. An integrated 1.5-A and 2-A (SRC-SNK)
peak gate drive output, clamped internally at 15.2 V
(typical), enables fast turn-on, turn-off, and easy
management of the external power switch without the
need for buffer circuits.
Low-distortion wave shaping of the input current
using average current mode control is achieved
without input line sensing, reducing the external
component count. In addition, the controller features
reduced current sense thresholds to facilitate the use
of small-value shunt resistors for reduced power
dissipation, especially important in high-power
systems. To enable low current distortion, the
controller also features trimmed internal current loop
regulation circuits for eliminating associated
inaccuracies.
