TEA1205AT - High efficiency DC/DC converter

Description

The TEA1205AT (see Fig.1) is a fully integrated DC/DC converter circuit using the minimum amount of external components.

It is intended to be used to supply electronic circuits with supply voltages of 3.3 or 5.

Features

  • Fully integrated DC/DC converter circuit.
  • Up conversion in 2 different modes.
  • High efficiency over wide load range.
  • Synchronizes to external high frequency clock.
  • Output power up to 3.6 W (typ. ) continuous, 8 W in GSM burst mode.
  • Low quiescent power consumption.
  • True current limit for Li-ion battery compatibility.
  • Shut-down function.
  • 8-pin SO package.
