NOTES:

6. In normal operation, where the device is supplied with voltage on the VIN pin, the VCC5V pin provides a 5V output capable of 75mA (min). When the

device is supplied by an external 5V supply on the EXTBIAS pin, the internal LDO regulator is disabled. The voltage at VCC5V should not exceed the

voltage at VIN at any time. (Refer to “Pin Descriptions” on page 3 for more details.)

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. 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.

10. Threshold voltage at PHASE pin for turning off the bottom MOSFET during DEM.

11. 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.

Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Block Diagram” on page 5 and “Typical

Application Schematics” on page 6. VIN = 4.5V to 60V, or VCC5V = 5V ±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)
