- Voltage Margining Using the TPS62130PDF, 79 Kb, File published: Dec 15, 2011
Voltage margining is a means of verifying the robustness of a product by intentionally adjusting its supply voltages to their limits and then evaluating the product’s performance to ensure that it still meets its specifications at the power supply’s extremes. The TPS62130 synchronous step-down dc-dc converter features an integrated output voltage scaling function that allows for +5% margining by u - TPS62130A Differences to TPS62130PDF, 247 Kb, File published: Apr 2, 2014
