Notes:

6. 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.

7. This is the total shutdown current with VIN = 5.6V and 60V.

8. Operating current is the supply current consumed when the device is active but not switching. It does not include gate drive

current.

9. When soft-start time is less than 4.5ms, tPGR increases. With internal soft-start (the fastest soft-start time), tPGR increases close

to its max limit 5ms.

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

11. Threshold voltage at the PHASE1 pin for turning off the buck bottom MOSFET during DE mode.

12. Threshold voltage between the CS+ and CS- pins for turning off the boost top MOSFET during DE mode.

Recommended operating conditions unless otherwise noted. Refer to “Block Diagram” on page 7 and “Typical Application Schematics”

on page 5. VIN = 4.5V to 60V, or VDD = 8V ±10%, C_VCC5V = 4.7µF, TA = -40°C to +125°C, Typical values are at TA = +25°C, unless

otherwise specified. Boldface limits apply across the operating temperature range, -40°C to +125°C. (Continued)
