Endicott Research Group (ERG) has released two high-efficiency, low-profile Smart Force LED driver boards as standard products for a wide range of industrial and medical LCDs. The SFDE (Economical) and SFDM (Mini) series provide full function power supplies with optimum power for high brightness as well as lower power consumption and lower cost in a compact size. Both driver boards measure less than 5mm in height; provide brightness stability over a wide input voltage, and can power up to six LED strings.Touting an excellent cost/performance ratio, the SFDE series provides a plug-and-play solution for backlighting LCDs up to 15-inches diagonal. The devices provide an input voltage range of 10-20V, with external PWM dimming to 500:1. The board measures 1.11-inch (28.2mm) x 3.10-inch (78.7 mm).

The SFDM is the most compact LED driver board ERG has developed to date, measuring only 0.96-inch (24.4mm) x 2.19-inch (55.6mm). It provides an input voltage range of 8-20V, with external PWM dimming to 250:1.

Both driver boards can be used with ERG's improved Smart Force LED rails as a drop-in replacement for CCFL rails for a number of OEM LCDs. Smart Force LED rails feature a proprietary ERG design that provides exceptionally good thermal management to keep the LEDs from overheating. The driver boards are available as standalone products from stock, or as kits that include the driver boards and LED rails, also available from stock.

The Smart Force SFDE LED driver board is priced at $15.73 in production quantities. The SFDM Series driver board is priced at $12.99 in production quantities. Delivery is typically four weeks ARO.
