Silicon Labs - CMOS Gate Drivers


Green standards are challenging power designers to deliver more energy-efficient, cost-effective, smaller, and
more reliable power delivery systems. A critical building block within ac-dc and isolated dc-dc power supplies is
the isolated gate driver. These trends push the need for greater power efficiency and increased isolation-device

Optocoupler-based solutions and gate-drive transformers have been the mainstay for switch-mode power supply
(SMPS) systems for many years, but fully integrated isolated gate driver products based on RF technology and
mainstream CMOS provide more reliable, smaller, and power-efficient solutions.

Legacy optocouplers and gate-drive transformers are quickly being replaced by fully integrated CMOS-based isolated gate drivers that provide more reliability in smaller, more power-efficient packages.
