Note 2: DC output accuracy specifications refer to the trip level of the error amplifier. When pulse skipping, the output slightly rises
(<0.5%) when transitioning from continuous conduction to no load.
Note 3: On-time and minimum off-time specifications are measured from 50% to 50% at the DHM and DHS pins, 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 4: The output fault-blanking time is measured from the time when FB reaches the regulation voltage set by the DAC code.
During normal operation (SUS = GND), the regulation voltage is set by the VID DAC inputs (D0 – D4). During suspend mode
(SUS = REF or high), the regulation voltage is set by the suspend DAC inputs (S0 – S1).
Note 5: Specifications to T A = -40 ° C and +100 ° C are guaranteed by design and are not production tested.
