1. Parameter tested in static condition during testing phase. Parameter value may change over dynamic

application condition.

2. LCM enables SLEEP mode at light load.

3. Specifications in the -40 to +125 °C temperature range are assured by characterization and statistical

correlation.

4. Not tested in production.
