*The LM2588 will require a heat sink in these applications. The size of the heat sink will depend on the maximum
ambient temperature. To calculate the thermal resistance of the IC and the size of the heat sink needed, see the
HEAT SINK/THERMAL CONSIDERATIONS section in the Application Hints.

SHUTDOWN CONTROL
A feature of the LM2588 is its ability to be shut down using the ON /OFF pin (pin 1). This feature conserves input
power by turning off the device when it is not in use. For proper operation, an isolation diode is required (as
shown in Figure 54).
