• Self-Protection Design (Including

Undervoltage, Overtemperature, Clipping, and

Short-Circuit Protection) With Error Reporting

• EMI Compliant When Used With

Recommended System Design

(1)

Achievable output power levels are dependent on the thermal

configuration of the target application. A high performance

thermal interface material between the package exposed

heatslug and the heat sink should be used to achieve high

output power levels.
