CONSONANCE
High-Voltage, Linear High-Brightness LED Driver IC
General Description:
The CN5501 current regulator operates from a 4V to 32V input voltage range and delivers up to a total of 1A to one or more strings of high-brightness LEDs. The output current of the CN5501 is adjusted by using an external current-sense resistor in series with the LEDs. An enable input allows wide-range “pulsed” dimming. The CN5501 is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 32V. An on-chip power MOSFET minimizes external ponents while providing ±5% output current accuracy. Also an EQ pin is adopted for equalizing LED...
