The LTC
converter that produces a regulated 5V output. The input
voltage range is 2.7V to 5V. Extremely low operating current
(typically 6 A with no load) and low external parts count (one
0.1 F flying capacitor and two small bypass capacitors at V
and V
battery-powered applications. The total printed circuit board
area of the application circuit shown below is only 0.045in
The part operates as a Burst Mode
voltage doubler to produce a regulated output. The part has
thermal shutdown capability and can survive a continuous
short circuit from V
5-pin SOT-23 package.
Burst Mode is a trademark of Linear Technology Corporation.
