The TPS61094 is a synchronous bi-directional buck/ boost converter with bypass switch between input and output. The device provides a power supply solution for E-meter and super capacitors backup power applications. The TPS61094 has wide input voltage range andoutput voltage up to 5.5 V. 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.
