Note 2: DC output accuracy specifications refer to the trip level of the error amplifier. The output voltage has a DC regulation higher

than the trip level by 50% of the output ripple. When pulse skipping, the output rises by approximately 1.5% when transition-

ing from continuous conduction to no load.

Note 3: On-time and minimum off-time specifications are measured from 50% to 50% at the DL_ and DH_ 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 might be different due to MOSFET switching speeds.s
