Isolated dc-dc controller ICs simplify transformer design
The RVP and RVS series from RECOM Power provide unregulated driver and rectification solutions for isolated power supplies up to 10W, enabling high integration and reinforced isolation with minimal external components.
The RVP series of unregulated dc-dc converter drivers supports input and output voltages up to 30V with a power rating of up to 10W. The family is divided into push-pull and full-bridge drivers to address different system requirements. The push-pull controllers include the RVP009 and RVP010, and RVP6501, the latter offering pin and function compatibility with the industry-standard SN6501 driver.
For designs prioritizing transformer simplicity, the RVP001, RVP003, RVP005 utilize a full-bridge topology, eliminating the need for a center-tapped primary winding on the transformer.
These drivers can be paired with the RVS002 or RVS004 secondary-side rectification ICs. The RVS series replaces rectifier diodes and dummy resistors, simplifying design and minimizing component count.
RECOM supports these ICs with a range of pre-tested RMR-series transformers to create discrete solutions that meet specific isolation requirements, ranging from 1,500V dc functional isolation to 8,000V dc reinforced isolation. This validated pairing of IC and transformer accelerates the prototyping process for isolated power stages. Custom voltage combinations up to 24V are also supported for high-volume applications.
