10.3 Thermal Considerations

In normal operation the LM5060 dissipates very little power so that thermal design may not be very critical. The

power dissipation is typically the 2 mA input current times the input voltage. If the application is driving a large

capacitive load application, upon shutdown of the LM5060, the load capacitor may partially, or fully, discharge

back through the LM5060 circuitry if no other loads consume the energy of the pre-charged load capacitor. One

application example where energy is dissipated by the LM5060 is a motor drive application with a large capacitor

load. When the LM5060 is turned off, the motor might also turn off such that total residual energy in the load

capacitor is conducted through the OUT pin to ground. The power dissipated within the LM5060 is determined by

the discharge current of 80 mA and the voltage on the load capacitor.
