Notes:

3. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.

4. The discharge function is active when the device is disabled (when enable is de-asserted or during power-up power-down when VIN < VUVLO).

The discharge function offers a resistive discharge path for the external storage capacitor for limited time.

5. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.

6. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper, with minimum recommended pad on top layer and thermal vias to bottom layer ground

plane.
