1 Guaranteed by design.

2 Measured between VIN and SW pins—includes bond wires and pin resistance.

3 Based on bench characterization. Measured with VIN = 12 V, VOUT = 1.2 V, load = 1 A, fSW = 1 MHz, and the output in regulation. Measurement does not include dead time.

4 Based on bench characterization. Measured with VIN = 15 V, VOUT = 12 V, load = 1 A, fSW = 600 kHz, and the output in regulation. Measurement does not include dead time.

5 This threshold is expressed as a percentage of the nominal output voltage.
