Enhance Power Efficiency with the CM6800UX Power Factor Correction Controller

Upgrade your power supply system with the CM6800UX Power Factor Correction (PFC) Controller, designed to optimize power efficiency and reliability. This controller enables power factor correction, reducing power line loading and stress on switching FETs. With integrated circuits for leading-edge PFC and trailing-edge pulse width modulation (PWM), it provides comprehensive control for switch mode power supplies.

The CM6800UX incorporates a 1A capable gate driver, minimizing the need for external driver circuitry and reducing component costs. Its low power requirements increase efficiency, resulting in improved overall system performance. In case of a sudden load drop, the overvoltage comparator turns off the PFC section, ensuring protection and safety.

Versatile Control for Switch Mode Power Supplies with PFC and PWM Integration

Featuring a 23V Bi-CMOS process, the CM6800UX offers excellent performance and reliability. It includes peak current limiting, input voltage brownout protection, and foldback current limit for short-circuit protection in the PWM section. The PWM section can operate in current or voltage mode up to 250kHz, with an accurate 50% duty cycle limit to prevent transformer saturation.

Key Features:

• Pin compatible with ML4800 and FAN4800
• Additional foldback current limit for the PWM section
• Synchronized leading-edge PFC and trailing-edge PWM in one IC
• Ultrafast PFC response with the Slew Rate Enhanced Transconductance Error Amplifier
• Low startup and operating current for improved efficiency
• Low total harmonic distortion (THD) and high power factor (PF)
• Reduces ripple current in the storage capacitor between PFC and PWM sections
• Configurable PWM operation in current mode or voltage mode
• Undervoltage control, overvoltage protection, UVLO, and soft start for enhanced control
