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 RdsON CMOS power switches with low parasitic capacitances and synchronous rectification.
