NOTES:
3. Specifications at -40°C and 85°C are guaranteed by design, not production tested.
4. In normal operation, where the device is supplied with voltage on the V_IN pin, the VCC_5V pin provides a 5V output capable of 60mA (min).
When the VCC_5V pin is used as a 5V supply input, the internal LDO regulator is disabled and the V_IN input pin must be connected to the
VCC_5V pin. (Refer to the Pin Descriptions section for more details.)
5. This is the total shutdown current with VIN = VCC_5V = PVCC = 5V.
6. Operating current is the supply current consumed when the device is active but not switching. It does not include gate drive current.
7. The peak-to-peak sawtooth amplitude is production tested at 12V only; at 5V this parameter is guaranteed by design.
8. Guaranteed by design; not production tested.
9. Not production tested; guaranteed by characterization only.
10. Guaranteed by design. The full scale current of 32µA is recommended for optimum current sample and hold operation. See the Feedback Loop
Compensation Section below.
