Texas Instruments UCC28180D UCC28180D PFC Controller IC 10.1 VDC to 21 & 7 mA Supply Lockout 96.5 % Duty Cycle SOIC-8

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.
