*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
Notes: 1. Depending on implementation of slope compensation, sub-harmonics have to be prevented.
2. The value of the minimum load current must be higher than the internal pull-up current at pin VCORE to ensure proper
function of the regulator.
