New Linear LED Drivers from Fairchild Semiconductor

Fairchild Semiconductor has introduced new linear LED drivers, the FAN5622, the FAN5624 and the FAN5626, for glucometers and handsets devices. The FAN5622/24/26 LED drivers have two, four and six channels, respectively.

The LED drivers reduce the number of components by removing extra passive components, which are normally used in series-boost LED drivers and charge pumps.

The LED outputs’ brightness levels are programmed with the help of a single-wire control interface. Users can apply digital pulses via the interface to turn on and off the light-emitting diodes and to program the linear dimming steps. This allows better dimming resolution by utilizing a simple technique to control the functionality. The LED drivers have a 92% peak efficiency, which increases battery life.

The LED drivers provide a simple design for component and design engineers and reduce the total solution space when compared to inductive boost or charge pump solutions. The FAN5622/24/26 LED drivers speed up the launch of portable designs and minimize the total bill of materials.

The FAN5622/24/26 LED drivers have a shut-down current of less than 1 µA and a 2.7 to 5.5 V input voltage range. The devices provide thermal, under-voltage and short-circuit protection.
