GENERAL
Please read Application Note 1 "General Operating Considerations" which covers stability, supplies, heat sinking,
mounting, current limit, SOA interpretation, and specification interpretation. Visit www.Cirrus.com for design tools
that help automate tasks such as calculations for stability, internal power dissipation, current limit; heat sink selec-
tion; Apex Precision Power’s complete Application Notes library; Technical Seminar Workbook; and Evaluation Kits.
CURRENT LIMIT
For proper operation, the current limit resistor (R
gram. For optimum reliability the resistor value should be set as high as possible. The value is calculated as follows;
with the maximum practical value of 16 ohms.
