產品總覽
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
