TPS61253A - 5-V / 4-A Boost Converter

General Description

The TPS61253x device provides a power supply solution for battery-powered portable applications.

With the input voltage ranging from 2.3 V to 5.5 V (TPS61253A) or 2.5 V to 5.5 V (TPS61253E), the device supports the applications powered by the Li-Ion batteries with the extended voltage range.

Key Features

  • Wide input voltage range from 2.3 V to 5.5 V (TPS61253A).
  • Wide input voltage range from 2.5 V to 5.5 V (Startup>2.6V, TPS61253E).
  • Fixed output voltage: 4.5 / 4.7 / 5.0 / 5.2 V / 5.25 V.
  • Two FETs integrated: 35-mΩ LS-FET, 60-mΩ HS- FET.
  • IOUT ≥ 1500-mA continuously at VOUT = 5 V and VIN ≥ 3 V (TPS61253A).
  • IOUT ≥ 1500-mA continuously at VOUT = 5.25 V and VIN ≥ 3 V (TPS61253E).
  • 42-µA quiescent current from input.
  • 4-A switching.
