TPS60230EVM-047: 20mA x5 @ 4V Max, 2.7 ~ 6Vin


The Texas Instruments TPS60230EVM-047 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS60230. This device is an efficient charge-pump-based current sink that can drive up to five white LEDs with 25mA each. Efficiency is improved by switching between a 1.0x and 1.5x mode, based on the input voltage.

This EVM is specifically designed and optimized to operate with a single-cell Li-Ion battery input. The default maximum current setting for this EVM is 20mA per LED. If desired, this EVM can easily be modified to supply higher or lower currents by appropriately selecting the ISET resistor, R1. Refer to the data sheet (SLVS516) for more information on adjusting the LED current.
