UCC28019A 8-Pin Continuous Conduction Mode (CCM) PFC Controller Features
8-Pin Solution Reduces External Components Wide-Range Universal AC Input Voltage Fixed 65-kHz Operating Frequency Maximum Duty Cycleof 98% (typ.)

Convertersin the 100Wto >2 kW Range Digital TV Home Electronics White Goods and Industrial Electronics Server and Desktop Power Supplies Description
The UCC28019A 8-pin active Power Factor
Correction (PFC) controller uses the boost topology
operatingin Continuous Conduction Mode (CCM).
The controlleris suitable for systemsin the 100Wto kW range overa wide-range universal ac line
input. Start-up current during undervoltage lockoutis
less than 200 μA. The user can control low power
standby mode by pulling the VSENSE pin below
0.77V.
Low-distortion wave shaping of the input current
using average current mode control is achieved
without input line sensing, reducing the external
component count. Simple external networks allow for
flexible compensation of the current and voltage
control loops. The switching frequencyis internally
fixed and trimmedto better than ±5% accuracyat
25°C. Fast 1.5-A peak gate current drives the
external switch.
Numerous system-level protection features include
peak current limit, soft over-current, open-loop
detection, input brown-out, and output
over/undervoltage. Soft-start limits boost current
during start-up.A trimmed internal reference provides
accurate protection thresholds anda regulation set-
point. An internal clamp limits the gate drive voltage 12.5V.
