UCCx81xA BiCMOS Power Factor Preregulator Features Controls Boost Preregulatorto Near-Unity Power
Factor Limits Line Distortion World Wide Line Operation Overvoltage Protection Accurate Power Limiting Average Current Mode Control Improved Noise Immunity Improved Feed-Forward Line Regulation Leading Edge Modulation 150-µA Typical Start-Up Current Low-Power BiCMOS Operation 12-Vto 17-V Operation Frequency Rangeof6 kHzto 220 kHz
Applications PC Power Consumer Electronics Lighting Industrial Power Supplies IEC6100-3-2 Compliant Supplies Less Than
300W
Description the UCC3818A family provides for active power The controller achieves shaping theac input lineto thatof the ac input mode control maintains line current. BiCMOS process, the offers new features such as lower power dissipation,
overvoltage protection,a shunt UVLO detect circuitry, leading-edge modulation techniqueto reduce ripple
currentin the bulk capacitor and an improved, low-
offset (±2 mV) current amplifierto reduce distortionat
light load conditions.
