TPS61121 - Synchronous Boost Converter

Download the TPS61121 datasheet PDF. This datasheet also covers the TPS61120 variant, as both devices belong to the same synchronous boost converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS6112x devices provide a complete power supply solution for products powered by either a onecell Li-Ion or Li-Polymer by either a one-cell Li-Ion or Li-Polymer battery, or a two- to four-cell Alkaline, NiCd, or NiMH battery.

Key Features

  • 1 Synchronous, 95% Efficient, Boost Converter With 500-mA Output Current From 1.8-V Input.
  • Integrated 200-mA Reverse Voltage Protected LDO for DC-DC Output Voltage Post Regulation or Second Output Voltage.
  • 40-µA (Typical) Total Device Quiescent Current.
  • Input Voltage Range: 1.8 V to 5.5 V.
  • Fixed and Adjustable Output Voltage Options up to 5.5 V.
  • Power Save Mode for Improved Efficiency at Low Output Power.
  • Low Battery Comparator.
