... Supply voltage source for low-voltage chip sets Portable computers Battery backup supplies Cameras. 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 R switches with low parasitic capacitances, and fully synchronous rectification ...

... SHDWN 8 shut-down input FUNCTIONAL DESCRIPTION Control mechanism The TEA1208T DC/DC converter is able to operate in either PFM (discontinuous conduction) or PWM (continuous conduction) mode. All switching actions are completely determined by a digital control circuit which uses the output voltage level as its control input. This special design enables the use of a pulse width and ...

... Down conversion: when the input voltage is lower than the target output voltage, but higher than 2.8 V, the P-type power MOSFET will stay conducting resulting in an output voltage being equal to the input voltage minus some resistive voltage drop. The current limiting function remains active. 6 Product specification TEA1208T ...

... High efficiency DC/DC converter External component selection I L1 NDUCTOR The performance of the TEA1208T is not very sensitive to the inductance value. Best efficiency performance over a wide load current range is achieved by using e.g. Coilcraft DO1608C, having an inductance and a saturation current level of 1 case the maximum output current is lower, other inductors are also suitable such as the small sized Coilcraft DT1608 range or Murata LQH4N series ...
