Power ICs - microBUCK® - Voltage Regulator
microBUCK® integrated voltage regulators (buck regulators) leverage Vishay's unique combination of discrete MOSFET design,
IC expertise, and packaging capability to provide cost-effective, high-performance integrated solutions that deliver a significant
reduction in board space requirements. This benefits the designer by giving more space for critical system functionality.
Typical applications include notebook, desktop, and server computers, digital HDTV, digital consumer applications, printers,
DSL, and STB applications, embedded applications and point of load power supplies.
