说明
- DC2079A, Demo Board is a 40VIN, 40VOUT LED driver. It generates its own PWMOUT waveform from its internal PWM generator for accurate PWM dimming with up to 33:1 brightness ratio. It accepts an input voltage from 5V to 30V and drives up to 32V of LEDs at 650mA. DC2079A features high efficiency at 350kHz switching frequency. At high LED string voltages up to 32V and 650mA of LED current, the single switch controller has 94.6% efficiency
