Introduction
The Texas Instruments TPS60250EVM-185 evaluation module (EVM) helps designers evaluate the
operation and performance of the TPS60250 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 TPS60250
contains a 1×/1.5× chargepump, as well as seven current sinks that are configured into a main display
bank of four or five WLEDs and a sub-display bank of two WLEDs. Additionally, the fifth main display
WLED can be configured to drive an aux display at up to 80 mA for backlighting a keypad or a weak
camera flash.
