NEXPERIA NCR32xx and 40 V NCR42xx series AEC-Q101 qualified constant current LED drivers drive low- and medium-power LEDs up to 250mA. The 16V devices are available in two package styles, the space-saving SOT457 (SC-74) and the SOT223 (SC-73), a slightly-larger option which delivers a higher-power capability of up to 1250 mW. LED drivers provide an accurate, stabilized output current of 10mA without an external resistor; if an external resistor is used then the output current is adjustable up to 250mA. Voltage overhead is low at 1.4V. For extra ruggedness, the junction temperature of the drivers is 150°C.
