TPS61281A - Wide- Voltage Battery Front-End DC/DC Converter

Download the TPS61281A datasheet PDF. This datasheet also covers the TPS61280A variant, as both devices belong to the same wide- voltage battery front-end dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS6128xA device provides a power supply solution for products powered by either by a Li-Ion, Nickel-Rich, Silicon Anode, Li-Ion or LiFePO4 battery.

The voltage range is optimized for single-cell portable applications like in smart-phones or tablet PCs.

Key Features

  • 1 95% Efficiency at 2.3MHz Operation.
  • 3µA Quiescent Current in Low IQ Pass-Through Mode.
  • Wide VIN Range From 2.3V to 4.8V.
  • IOUT ≥ 4A (Peak) at VOUT = 3.35V, VIN ≥ 2.65V.
  • Integrated Pass-Through Mode (35mΩ).
  • Programmable Valley Inductor Current Limit and Output Voltage.
  • True Pass-Through Mode During Shutdown.
  • Best-in-Class Line and Load Transient.
  • Low-Ripple Light-Load PFM Mode.
  • In-Situ Customization with On.
