TPS61251 - Boost Converter

General Description

The TPS61251 device provides a power supply solution for products powered by either a three-cell, NiCd or NiMH battery, or a one-cell Li-Ion or Lipolymer battery.

The wide input voltage range is ideal to power portable applications like mobile phones, solid state drives (SSD) and wireless modems.

Key Features

  • 1 Resistor Programmable Input Current Limit.
  • ±10% Current accuracy at 500 mA over full temperature range.
  • Programmable from 100 mA up to 1500 mA.
  • Snooze mode draws only 2 μA (typical) quiescent current.
  • Designed to charge large capacitor values in the Farad range.
  • Up to 92% Efficiency.
  • Power good indicates appropriate output voltage level even in shutdown.
  • VIN range from 2.3 V to 6 V.
  • Adjustable output voltage up to.
