The TPS61122PW from Texas Instruments is a versatile synchronous boost converter featuring an integrated LDO for post-regulation. This device is designed to provide a complete power supply solution for products powered by single-cell Li-Ion or Li-Polymer batteries, or multi-cell alkaline batteries.
Key electrical specifications include an input voltage range of 1.8V to 5.5V and a typical quiescent current of 40µA. The boost converter offers up to 500mA output current with 95% efficiency and a switch current limit of 1600mA. The integrated LDO can provide up to 200mA output current. The device supports fixed and adjustable output voltage options up to 5.5V.
Operating within a temperature range of -40°C to 85°C, the TPS61122PW is suitable for various portable equipment. It is available in a compact 16-TSSOP package, measuring 4.40mm in width, making it ideal for space-constrained designs.
Applications include handheld and mobile devices, dual input or dual output systems, and simple Li-Ion to 3.3V conversion. The converter can be disabled to minimize battery drain, and the load is completely disconnected during shutdown. A power good output simplifies control of cascaded power supply stages or microprocessors.
