DESCRIPTION
GENERAL DESCRIPTION
The TEA1204T 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, 3.6 or 5.0 V from 2, 3 or 4 NiCd cell
batteries or one LiIon battery at an output power level up
to 3.6 W (typ.) continuously, or 8 W in GSM TDMA (1 : 8)
burst mode. Efficient, compact and dynamic power
conversion is achieved using a novel, digitally controlled
Pulse Width and Frequency Modulation (PWFM) like
control concept, integrated low R
switches with low parasitic capacitances and synchronous
rectification.
