Performance Information (cont’d)

Typical Thermal Characteristics (cont’d)

The theoretical calculations of these relationships

show the safe operating area of the CM3196 in the

SOIC package.

Thermal characteristics were measured using a dou-

ble-sided board with two square inches of copper area

connected to the GND pins for "heat spreading."

Measurements showing performance up to a junction

temperature of 150°C were performed under light load

conditions (5mA). This allows the ambient temperature

to be representative of the internal junction tempera-

ture.

Note: The use of multi-layer board construction with

separate ground and power planes will further enhance

the overall thermal performance.
