Use of LEDs (light emitting diodes) in LCD backlights is rapidly growing from smaller LCD panels to applications across the entire spectrum of LCD sizes. The new generation of high-bright LEDs (HBLEDs) provide a quantum leap in brightness, as well as higher reliability, more durability, lower power consumption, better dimming, and operation over a wider temperature range. 

They also create new challenges for the power supply driving the LED BLU, challenges that cannot be met by the many single chip ICs available on the market. Getting optimum performance from LED BLUs requires a full-function power supply. ERG, the specialist in power solutions for LCD backlights since 1979, has introduced a new generation of LED backlight drivers and LED rails called Smart Force™ LED Solutions. ERG has introduced the ERG Smart Kits™ for popular displays that will provide everything you will need to get your backlight OEM panel up and running.

Thinking single-chip IC? Think again. 

A chip may look good for your LED BLU application at first, but consider the voltage the device needs across it to accurately regulate current.  Is there enough voltage across the device remaining to light the LED string and provide proper current regulation?

What temperature are the LED voltages specified at? Say it is 25º C (approx. 77º F). If you were to take the LED string below 25º C (unlit) and then power the string, the LEDs may not light at all because the LED string voltage is greater.

ERG Smart Force™ LED Driver Boards are designed to account for this voltage change and can light across the entire normal operating range of temperatures, with no time or expense devoted to designing a boost circuit.
