LM3404HVEVAL

Оценочная плата ШИМ драйвера светодиода LM3404HV с тепловой защитой.

The LM3404HVEVAL is an evaluation board for LM3404HV, a buck regulator derived controlled current source designed to drive a series string of high power, high brightness LEDs (HBLEDs) such as the Luxeon K2 Emitter at forward currents of up to 1A. When using the pin for pin compatible LM3404HV the upper bound of input voltage is 75V. The converter output voltage adjusts as needed to maintain a constant current through the LED array. The LM3404HV is a true step down regulator with an output voltage range extending from a VO(MIN) of 200mV (the reference voltage) to a VO(MAX) determined by the minimum off time (typically 300ns). It can maintain regulated current through any number of LEDs as long as the combined forward voltage of the array does not exceed VO(MAX).
