GENERAL DESCRIPTION
The TEA1207T is a fully integrated DC/DC converter.
Efficient, compact and dynamic power conversion is
achieved using a novel digitally controlled concept like
Pulse Width Modulation (PWM) or Pulse Frequency
Modulation (PFM), integrated low RDSon CMOS power
switches with low parasitic capacitances, and fully
synchronous rectification.
The device operates at 275 kHz switching frequency
which enables the use of external components with
minimum size. 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.
