maximum load current should be derated as the ambient
temperature approaches 125°C.
Power dissipation within the LT3684 can be estimated by
calculating the total power loss from an efciency measure-
ment and subtracting the catch diode loss and inductor
loss. The die temperature is calculated by multiplying the
LT3684 power dissipation by the thermal resistance from
junction to ambient.

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.
