The TPS61122PWR from Texas Instruments is a synchronous boost converter with an integrated LDO, designed to provide a complete power supply solution for battery-powered products. It supports an input voltage range of 1.8 V to 5.5 V and can deliver up to 500 mA of output current from the boost converter, with an integrated 200 mA LDO for post-regulation. The device boasts high efficiency, reaching up to 95%, and a low quiescent current of 40 µA typical.
This converter is ideal for applications such as handheld and mobile devices, offering flexible output voltage options that can be adjusted externally or are fixed internally. It features a power-save mode for improved efficiency at low output power and includes a low battery comparator. The TPS61122PWR also incorporates overtemperature protection and a power good output.
Packaged in a 16-TSSOP with a 4.40mm width, the TPS61122PWR is designed for surface mount applications. Its load disconnect feature during shutdown helps minimize battery drain, and a low EMI converter design reduces radiated electromagnetic energy. The device operates within a temperature range of -40°C to 85°C.
