TPS61291DRVR TI Voltage Regulators - DC DC Switching Regulators
The TPS61291 is a boost converter with an integrated VOUT switch and a load switch, operating from 0.9 V to 4.85 V input and delivering a fixed 5-V output. It is specifically designed for battery-powered applications that require a 5-V rail only when needed, with the ability to bypass the input directly to the output when the input voltage exceeds 5 V. Quiescent current is 2.5-µA typical in bypass mode. Packaged in a 6-pin WSON (DRV), it is ideal for portable devices that run from 1-cell Li-Ion or 2-cell alkaline batteries. Applications include portable medical devices, wireless sensors, and remote controls requiring intermittent 5-V power with ultra-low standby consumption.
