Nexperia Launches Industry-First LED Drivers in DFN Package with Side-Wettable Flanks
Nexperia, the expert in essential semiconductors, today announced a new range of LED drivers in the space-saving DFN2020D-6 (SOT1118D) package. This case style features side-wettable flanks (SWF) which facilitate the use of AOI (automated optical inspection), and improve reliability. This is the…
Features and Benefits:
• Stabilized output current of 10 mA without external resistor
• Stabilized output current adjustable up to 250 mA when an external
resistor is used
• High current accuracy at supply voltage variation
• Low voltage overhead of 1.4 V
• Reduces component count and board space
• High power dissipation of 530 mW
• Digital PWM input up to 10 kHz frequency for NCR321PAS
• AEC-Q101 qualified
Applications:
• Constant LED driver
• Generic constant current source
• Automotive applications (for example: interior lighting, dash board,
instrumentation, number plate light)
• Increase stabilized output current by paralleling drivers
With a footprint of just 2x2 mm and a low profile of 0.65 mm, the new DFN2020D-6 LED drivers are available in NPN and PNP technology. They feature an output current of up to 250 mA (NCR32x types) and a maximum supply voltage of 75 V. Their high thermal power capability is at least equal to any other package for LED drivers.
The use of side-wettable flanks not only enables AOI techniques to be used - which is especially important for automotive customers – but also improves reliability. Devices with side-wettable flanks exhibit a greater resistance to shear forces, and can handle greater board flexing without cracking than devices without side-wettable flanks.
Commented Frank Matschullat, product group manager at Nexperia: "The new DFN2020D-packaged parts with SWF address the concerns of various sectors – size, performance, ruggedness – so they are a perfect match for many diverse applications in general lighting, white goods and automotive. Nexperia is committed to deliver industry's broadest discrete portfolio in DFN technology, so introducing LED drivers in this rugged, space-saving package is a natural step. However, parts are also available in leaded SMD styles so customers can choose which to use."
Four DFN2020D-6 LED drivers are in mass production now. More information including product specs and datasheets is available at www.nexperia.com/led-driver
