具有主动式功率因数校正和相位调光解码器的 LED 驱动器

The LM3450/50A is a power factor controller (PFC) with separate phase dimming decoder. The PFC regulates the output voltage while maintaining excellent power factor. The phase dimming decoder interprets the phase angle and remaps it to a 500Hz PWM output. This device is ideal for implementing a dimm • Critical Conduction Mode PFC\n• Over-Voltage Protection\n• Feedback Short Circuit Protection\n• 70:1 PWM Decoded From Phase Dimmer\n• Analog Dimming\n• Programmable Dimming Range\n• Digital Angle and Dimmer Detection\n• Dynamic Holding Current\n• Smooth Dimming Transitions\n• Low Power Operation\n;
