RECOM 70W Buck-Driver Powers Longer LED-Strings and Larger Multi-Chip Arrays

November 21, 2011 by Jeff Shepard

RECOM Power Inc. introduced its RCD-48 series, a step-down constant current source designed for driving high power LED applications. With input voltage up to 60Vdc and constant current outputs of 350, 500, 700 and 1200mA the RCD-48 Series provides power up to 70W. A fixture using the full wattage could possible replace a conventional light that could have used up to 350W. The new buck-driver is well suited for operation with the new longer LED-chains and larger multi-chip arrays – a real technical achievement.

The RCD-48-drivers are dimmable down to zero with external digital (PWM) or analogue control. The PWM control input can be directly connected to a microcontroller. Efficiency is rated at 96%, with an operating temperature range -40 and +85°C. The modules are available with pins for PCB mounting or with flying leads for non pcb applications. While the powerful 1200mA version features a metal case, the smaller models are designed in plastic cases. All types are certified to EN/UL-60950-1. The MTBF is specified at MIL-HDBK217F with 1.7 million hours.

Samples are now available by leading distributors from stock.
