SFDK LED driver board

From Endicott Research Group (ERG) come two LED driver boards that provide compact, economical products to OEM panel designers looking to get the maximum performance out of their displays.

The new SFDK series is a high-efficiency, dual-output driver board with connectors on both sides of the PCB. It provides a plug-and-play solution for powering LED BLUs in LCDs up to 22-inch diagonal. The SFDK offers flat panel compatible (FPC) headers in addition to the standard wire-to-board connections, with the interface between the driver and panel consisting of 0.5mm flat flex cable (FFC) with six, eight, 10 or 12 positions, depending on the display. It has a maximum current of 320mA and can power up to eight LED strings at a maximum of four on each side.

The SFDK has an extremely low profile (<8mm high) and a compact size29.2mm x 116.5mm. It provides brightness stability over a wide input voltage (10V to 20V, with 5V available), external PWM dimming to 500:1, and is compatible with a number of OEM LED-backlit panels.

ERG's SFD2E LED driver is a new version of ERG's compact SFDE driver (E for economical) that packs high power into a compact board. Aimed at high-power, high-brightness LED BLUs used in LCDs in the 10.4-inch to 24-inch diagonal range, it can efficiently drive up to eight LED strings from one output at a maximum current of 480mA. It features a wide input voltage design (8V to 20V), external PWM dimming to 500:1 and onboard dimming to 255:1. The SFD2E measures 28.32mm x 116.5mm, with a low profile of less than 10mm. It is available with a J12 output connector that is FFC/FPC compatible. The SFD2E is designed for compatibility with a variety of OEM LCD panels

The LED driver boards are priced at approximately $20 in production quantities. Delivery is typically four to six weeks A.R.O.
