Vishay
Document Number: 10116
Revision 06-Apr-04
DESCRIPTION
The DC/DC converter provides fully integrated synchronous
Buck or Boost converter solution for the latest one-cell lithium
ion cellular phones. Its input voltage is between 2.5V to 6V
capable of delivering up to 4A output current. An external
resistor according to the formulas respectively, can adjust
an output voltage between 0.8V, 0.9V to 1.3V and 1.35V to
4.5V for Buck and 3.3V to 6V for Boost.
