Product Overview

The UCC28180D is a 8-pin active Power-Factor Correction (PFC) Controller operates under continuous conduction mode (CCM) to achieve high power factor, low current distortion and excellent voltage regulation of boost pre-regulators in AC to DC front-ends. The controller is suitable for universal AC input systems operating in 100W to few-kW range with the switching frequency programmable between 18 to 250kHz, to conveniently support both power MOSFET and IGBT switches. An integrated 1.5 and 2A (SRC-SNK) peak gate drive output, clamped internally at 15.2V (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.
  • Trimmed current loop circuits for low iTHD
  • Reduced current sense threshold
  • Average current-mode control
  • Soft over current and cycle-by-cycle peak current limit protection
  • Output overvoltage protection with hysteresis recovery
  • Audible noise minimization circuitry Open loop detection
  • Enhance dynamic response during output overvoltage and undervoltage conditions
  • Burst mode for no load regulation
  • Green product and no Sb/Br

Applications

Power Management, Industrial

Warnings

Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
