... As an SP6122 application example, we will use the circuit from the SP6122 Evaluation Board Manual. This evaluation board uses the Sipex SP6122ACU, 1.25V adjustable PFET controller to realize a 3.3V to 1.9V step down converter. The board is opti- mized for 1A – 4A operation and has an R over current trip threshold of about ...
