Description

UCC3818D SOP16 SMD Power Factor Corrector chip Pre Regulator

Designed in Texas Instrument’s BiCMOS process, the UCC3818D offers new features such as lower start-up current, lower power dissipation,
overvoltage protection, a shunt UVLO detect circuitry, a leading-edge modulation technique to reduce ripple current in the bulk capacitor, and an improved, low offset (±2-mV) current amplifier to reduce distortion at light load conditions.

DESCRIPTION: The UCC3818D family provides all the functions necessary for active power factor-corrected pre regulators. The controller achieves near-unity power factor by shaping the AC input line current waveform to correspond to that of the AC input line voltage. Average current mode control maintains stable, low distortion sinusoidal line current.
