Low IDDQ PMIC for Battery Energy Harvesting
Applications
The TPS65290 is an integrated PMIC for flow-meter system, low-power energy-harvesting, medical,
consumer and commercial battery operation application. This EVM helps the evaluation of TPS65290 for
your actual system. TPS65290 can be controlled by SPI using the USB2ANY kit.
