Note 1: Output voltage accuracy specifications apply to DAC voltages from 0.925V to 2V. Includes load-regulation error.
Note 2: On-Time specifications are measured from 50% to 50% at the DH pin, with LX forced to 0, 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 3: Specifications to -40°C are guaranteed by design and not production tested.
