NOTES:

6. Thermal impedance measured in still air on the ISL95210EVAL1Z REV B evaluation board with 800kHz setup. See AN1485.

7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

operating temperature range (-10°C to +100°C for ISL95210HRZ; -40°C to +100°C for ISL95210IRZ).
