The TPS61120PWG4 from Texas Instruments is a synchronous boost converter featuring an integrated 200-mA LDO for post-regulation or a second output voltage. It is designed to provide a complete power supply solution for products powered by single-cell Li-Ion or Li-Polymer batteries, or two- to four-cell Alkaline, NiCd, or NiMH batteries.
This device offers a high efficiency of 95% and operates with an input voltage range of 1.8 V to 5.5 V. The boost converter has a maximum output current of 500 mA and a switch current limit of 1.6 A. The integrated LDO can supply up to 200 mA. The output voltage can be fixed or adjustable, up to 5.5 V.
Key features include a low quiescent current of 40 µA typical, power-save mode for improved efficiency at low output power, low battery comparator, and power good output. The converter can be disabled to minimize battery drain, and the load is completely disconnected during shutdown. A low-EMI mode is implemented to reduce radiated electromagnetic energy.
The TPS61120PWG4 is available in a 16-TSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for various portable equipment applications.
