Texas Instruments TPS61094EVM-066 Converter Evaluation Module (EVM) is designed to help evaluate the TPS61094. The TPS61094 is a synchronous bi-directional buck/boost converter with a bypass switch between input and output. The device provides a power supply solution for E-meter and supercapacitors backup power applications. The Texas Instruments TPS61094 has a wide input voltage range and output voltage up to 5.5V. When the TPS61094 works in buck mode charging a supercap, the charging current and the charge termination voltage are programmable with two external resistors. When the TPS61094 works in boost mode, the output voltage is programmable with an external resistor.
