TPS61040 Boost Converter Evaluation Module for White LED Supply
This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
The TPS61040EVM-002 is an evaluation tool for the SOT-23 TPS61040 inductive boost converter which can supply voltages up to 28V from input voltages in the range of 1.8V to 6V.
The EVM is configured as white LED bias supply and the TPS61040 is set up to generate 20mA of bias current into four white LEDs from a single cell Li ion battery. The EVM can be modified to accomodate other battery chemistries or applications. The TPS61041 can be evaluated simply by replacing the TPS61040 IC on the EVM.
