NOTES:

3. In normal operation, where the device is supplied with voltage on the VIN 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 VIN input pin must be connected to the

VCC_5V pin. (Refer to the “Pin Descriptions” on page 10 for more details.)

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

7. Limits should be considered typical and are not production tested.

8. Limits established by characterization and are not production tested.

9. Established by characterization. The full scale current of 32µA is recommended for optimum current sample and hold operation. See the

“Feedback Loop Compensation” on page 13.

Electrical Specifications

Recommended operating conditions unless otherwise noted. Refer to “Block Diagram” on page 3 and “Typical

Application Schematic” on page 4. VIN = 5.6V to 24V, or VCC_5V = 5V ±10%, TA = -40°C to +85°C, Typical

values are at TA = +25°C. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise

specified. Temperature limits established by characterization and are not production tested. (Continued)
