Vishay Intertechnology Inc. (Malvern, PA) announced its new FX5959G701ADJ, a fully integrated, constant current source module to the FunctionPAK™ family of BGA-packaged dc-dc converters. It is intended for use in end products, including bike lamps, headlamps, flashlights, medical instrumentation, general and emergency alarm lighting, design and architectural lighting, interior and runway lights, outdoor accent lighting, household appliances, and other systems requiring a small design.
As a complete converter solution requiring no external components, the new FX5959G701ADJ converter drives power LEDs rated for operation at or above 300 mA by being connected with the LED and a low voltage source, such as a battery. The constant current source module ensures the full load life of LEDs without exceeding the applicable LED voltage. The new converter module incorporates 20 components and a dc-dc converter in a single BGA package measuring 0.59 in x 0.59 in x 0.126 in (15 mm x 15 mm x 3.2 mm). The FX5959G701ADJ provides an input-voltage range of 2.5 V to 6 V. It is rated for an output power of 15 W and a maximum current of 2.5 A. Each converter draws 1 mA of current in shutdown mode. The BGA package is rated for the full industrial temperature range of -40 °C to +85 °C.
Samples of the new FX5959G701ADJ are available now, with lead times of eight weeks for production quantities. Pricing for US delivery in 10,000-piece quantities starts at $7.50 per piece.
