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