The VRM10 non-isolated DC-DC converters are designed to meet
the exceptionally fast transient response requirements of today’s
microprocessors and fast switching logic in a compact size at a
very affordable price. Advanced circuit techniques, component
selection and placement optimization, state-of-the-art thermal
packaging, and surface-mount technologies provide a high power
density, highly reliable, and very precise voltage regulation system
for advanced microprocessors.
