Note 1: On-time specifications are measured from 50% to 50% at the DH pin, with LX forced to GND, BST forced to 5V, and a

500pF capacitor from DH to LX to simulate external MOSFET gate capacitance. Actual in-circuit times may be different due

to MOSFET switching speeds.

Note 2: The output fault blanking time is measured from the time when FB reaches the regulation voltage set by the DAC code.

During power-up, the regulation voltage is set by the boot DAC code (B0–B2). During normal operation (SUS = low), the

regulation voltage is set by the VID DAC inputs (D0–D5). During suspend mode (SUS = high), the regulation voltage is set

by the suspend DAC inputs (S0–S2).

Note 3: Specifications to TA = -40°C to +100°C are guaranteed by design and are not production tested.
