3.234/3.201

3.366/3.399

Efficiency

VIN = 12V, ILOAD = 3A

(1)

Typical values are determined with TA = TJ = 25°C and represent the most likely norm.

(2)

All limits are ensured at room temperature (standard type face) and at temperature extremes (bold type face). All room temperature

limits are 100% tested during production with TA = TJ = 25°C. All limits at temperature extremes are ensured via correlation using

standard Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
