SLVSFH6C January 2021 – December 2021 TPS61094
The TPS61094 is a 60-nA quiescent current synchronous bi-directional buck/boost converter with a bypass switch between the input and output. The TPS61094 can operate with a wide input voltage from 0.7 V to 5.5 V and output voltage from 1.8 V to 5.5 V. The device provides an ultra-low power solution optimized for applications that require ultra-low quiescent current, use a supercap or battery as backup power supply, or both. The TPS61094 has two typical application circuits. One is the pure boost with bypass function, as shown in Figure 8-1, which connects the SUP pin and VIN pin together. The other is the supercap backup application, which separates the SUP pin and VIN pin, as shown in Figure 8-14, which can charge supercap or boost supercap to power the output.
