The Texas Instruments TPS60255EVM-262 evaluation module (EVM) helps designers evaluate the
operation and performance of the TPS60255 white LED (WLED) driver for applications that are powered
with one Li-ion or Li-polymer cell and require two or three separate banks of WLEDs. The TPS60255
contains a 1 × /1.5 × chargepump, as well as one group of four 25mA WLED current regulators, one group
of two 25 mA WLED current regulators and a 80mA LED current regulator, capable of driving several
WLEDs in parallel. Each group's current level is independently controllable by three independent
brightness registers and five ON/OFF bits via a single-wire interface (EasyScale
