Introduction

AI Translation

The TPS61291 is a boost converter with pin selectable output voltages and an integrated bypass mode. In bypass operation, the device provides a direct path from the input to the system and allows a low power micro controller (MCU) such as the MSP430 to operate directly from a single 3V Li-MnO2 battery or dual alkaline battery cells.

Features

AI Translation
  • Input Voltage Range 0.9V to 5V
  • Startup Voltage 1.5V at 20mA Load
  • Pin Selectable Output Voltages: 3.3V, 3V, 2.5V
  • 15nA typical Quiescent Current in Bypass Mode
  • 5.7μA typical Quiescent Current in Boost Mode
  • Bypass Switch from VIN to VOUT, ΔIout>200mA at 3.3V VOUT, VIN=1.8V
  • Internal Feedback Divider Disconnect (Bypass Mode)
  • Controlled Bypass Transition Prevents Reverse Current into Battery
  • Power-Save Mode at Light Loads
  • Overtemperature Protection
  • Redundant Overvoltage Protection
  • Small 2mm x 2mm SON 6-pin package

Applications

AI Translation
  • Metering (Gas, Water, Smart Meters)
  • Remote Controls
  • Home Security / Home Automation
  • Single 3V Li-MnO2 or 2x1.5V Alkaline Cell Powered Applications
