Description

The PMP6886 reference design provides 2.5V at 5A from a standard 48V telecom input with greater than 88% efficiency. This design uses the UCC2897A active clamp controller along with TI NexFET synchronous rectifiers. The low gate thresholds of the CSD16323Q3 and CSD16406Q3 allow them to be driven directly from the transformer windings. The circuit is built in an industry standard 1/16 brick footprint. Auxilliary features of this design include remote sense, output over-voltage protection, output voltage trim and primary side enable control.
