Flyback, Forward & Isolated Controllers

Analog Devices’ growing portfolio of primary and secondary side controllers provides a simple and cost-effective replacement of dc-to-dc converter bricks used in backplane power conversion. The primary side switching regulator controllers are configurable in flyback controllers, single- or dual-transistor forward converters, push-pull converters, or full-bridge converters up to 1.5 kW. Similarly, the secondary side controllers provide synchronous rectification, drive, or postregulation.
