High Perf Single Ended to Diff Active Interface for High Speed ADC Developed by Dallas Logic Corp : Dallas Logic Corporation
TIDA-00294: This reference design uses the ADC34J22 12b 50Msps JESD204B data converter and the THS4541 fully differential amplifer to demonstrate how to design a high performance active interface for high speed ADCs. This type of circuit can be used in sensor front end, motor control, and test and measurement applications. The circuit model and derivation of the design equations is presented along with the actual implementation on a PCB. Results of this implementation are presented to show very similar performance as compared to a passive AC coupled transformer interface.
18Vdc-54Vdc Input, 24V @ 5A Output, Active Clamp Forward
PMP4844: The PMP4844 reference design provides an isolated 24V output at 120W from an 18V to 54V telecom input with up to 94% efficiency. This design uses the UCC2897A active clamp controller along with an ISO721 digital isolator and TPS28225 to drive synchronous rectifiers. The circuit is built in an industry standard Half-Brick footprint.
