CN5501

CONSONANCE High-Voltage, Linear High-Brightness LED Driver IC CN5501 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 components while providing ±5% output current accuracy. Also an EQ pin is adopted for equalizing LED current among multiple CN5501 used in parallel. Additional features include a 5V regulated output and thermal regulation, etc. The CN5501 is available in a thermally enhanced 8-pin SOP package and 8-pin DFN package.
