If TJmax is internally limited to 150
°
C, then the MC33263
can dissipate up to 595 mW @ 25
°
C.
The power dissipated by the MC33263 can be calculated
from the following formula:
Ptot
Vin
Ignd(Iout)

or

If a 150 mA output current is needed, the ground current
is extracted from the data–sheet curves: 6.5 mA @ 150 mA.
For a MC33263NW28R2 (2.8 V), the maximum input
voltage will then be 6.48 V, a rather comfortable margin.
Typical Application
– The following figure portraits the
typical application for the MC33263 where both
input/output decoupling capacitors appear.

As for any low noise designs, particular care has to be
taken when tackling Printed Circuit Board (PCB) layout.
The following figure gives an example of a layout where
stray inductances/capacitances are minimized.

This layout is the basis for an MC33263 performance
evaluation board where the BNC connectors give the user an
easy and quick evaluation mean.
