TPS61021A - 3-A Boost Converter

Description

The TPS61021A provides a power supply solution for portable or smart devices powered by alkaline, NiMH, Li-Mn, or Li-ion batteries.

The TPS61021A is capable of outputting 3.3-V voltage and 1.5-A current from a battery discharged to as low as 1.8 V.

Features

  • 1 Input Voltage Range: 0.5 V to 4.4 V.
  • 0.9 V Minimum Input Voltage for Startup.
  • Output Voltage Setting Range: 1.8 V to 4.0 V.
  • 91% Efficiency at VIN = 2.4 V, VOUT = 3.3 V and IOUT = 1.5 A.
  • 2.0-MHz Switching Frequency.
  • IOUT > 1.5 A at VOUT = 3.3 V when VIN > 1.8 V.
  • 17-µA Typical Quiescent Current.
  • ±2.5% Reference Voltage Accuracy over -40°C to 125°C.
  • PFM Operation Mode at Light Load.
  • True Disconnection Betwee.
