GENERAL DESCRIPTION
The TEA1208T is a fully integrated DC/DC converter.
Efficient, compact and dynamic power conversion is
achieved using special digital control concepts - Pulse
Width Modulation (PWM) and Pulse Frequency
Modulation (PFM), integrated low RDSon CMOS power
switches with low parasitic capacitances, and fully
synchronous rectification.
The device operates at a switching frequency of 275 kHz
requiring only minimum sized external components.
Deadlock is prevented by an on-chip undervoltage lockout
circuit.
Efficient behaviour during short load peaks and
compatibility with Li-ion batteries is guaranteed by an
accurate current limiting function.
