Monolithic 65 V, 8 A Step-Down Regulators with Fast Transient Response and Ultralow EMI Emissions
When designing buck converters for 48 V bus systems, power supply engineers are inclined to choose controller solutions (external MOSFETs) over much smaller monolithic regulators (internal MOSFETs), since few monolithic regulators are able to handle such high input voltages and most are limited to output currents less than 5 A.
This paper introduces 65 V synchronous step-down monolithic regulators capable of supporting 8 A outputs. Their architecture enables exceptional EMI performance regardless of layout.
