The Nexperia USA Inc. NCR421UX is a linear LED driver IC housed in a compact SOT-457 (SC-74) 6-TSOP package. This device is designed to provide a stabilized output current for LED applications, with adjustable output current up to 150 mA when an external resistor is used. It features a high current accuracy, low voltage overhead of 1.4 V, and a supply voltage capability of up to 40 V.
The NCR421UX supports digital PWM input for dimming control up to 10 kHz frequency, making it suitable for automotive applications such as interior lighting, dashboards, and instrumentation. Its integrated design reduces component count and board space. The device operates within an ambient temperature range of -55°C to 150°C and has a high power dissipation capability of 750 mW.
Key features include its linear topology, surface mount capability, and AEC-Q101 qualification, ensuring reliability in demanding environments. The NCR421UX is an efficient solution for generic constant current source requirements.
