voltage on the VCC1 pin must be >= 16 V (15 V if LLC is not used).
For example, with IOUT = 500 mA:
Equation 2
Power dissipated in this resistor is:
Equation 3
It is recommended to bypass the VCC1 and VCC2 pins using 220 nF electrolytic capacitors.

IPPAK mounting and thermal considerations
First, it should be noted that the tab is directly connected to the GND pin, so care must be
taken when the device is connected to a heat-sink. If the heat sink is at a different voltage
than the ground, an electrical insulator must be added between the tab and the heat sink at
the cost of an increase in the thermal resistance. For better thermal performance, an
isolated heat sink or connection to ground is recommended.
Several clips can be used depending on the heat sink type:
●
Saddle clips (Figure 7) for slim heat sinks
●
U-clips (Figure 8) for thick heat sinks
●
Dedicated clips for special shaped heat sinks
