LT1913
APPLICATIONS INFORMATION
sistance. Because of the large output current capability of
the LT1913, it is possible to dissipate enough heat to raise
the junction temperature beyond the absolute maximum of
125°C. When operating at high ambient temperatures, the
maximum load current should be derated as the ambient
temperature approaches 125°C.
Power dissipation within the LT1913 can be estimated by
calculating the total power loss from an ef?ciency measure-
Other Linear Technology Publications
Application Notes 19, 35 and 44 contain more detailed
descriptions and design information for buck regulators
and other switching regulators. The LT1376 data sheet
has a more extensive discussion of output ripple, loop
compensation and stability testing. Design Note 100
shows how to generate a bipolar output supply using a
buck regulator.
ment and subtracting the catch diode loss and inductor
loss. The die temperature is calculated by multiplying the
LT1913 power dissipation by the thermal resistance from
junction to ambient.
