GENERAL DESCRIPTION
The TEA1210TS 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 R CMOS power
switches with low parasitic capacitances, and fully
synchronous rectification.
The device operates at 600 kHz switching frequency
which enables the use of external components with
minimum size. The switching frequency can be locked to
an external high-frequency clock.
Optionally, the device can be kept in the Pulse Width
Modulation (PWM) mode regardless of the load applied.
Deadlock is prevented by an on-chip undervoltage lockout
circuit.
Two selectable current limits in upconversion mode enable
efficient battery use even at highly dynamic loads such as
cellular phone electronics.
