2.4W multi-output PSR flyback reference design for bias supplies
PMP23546
概述
This reference design uses TPS7H5020-SEP as a primary-side regulated (PSR) flyback converter. The input accepts a 22V to 36V range to generate a 12V bias referenced to primary ground and another 12V output that can be referenced to another return. This reference design can be used to provide bias power for isolated reference designs, like PMP23391. In this design the controller, half-bridge drivers and TI gallium nitride field-effect transistors (FET) are chosen to meet radiation for geostationary orbit (GEO). These components can be swapped out to meet other mission specifications.
特性
- GEO class radiation performance components
- Greater than 5% output regulation across loading conditions
- Generates two 12V bias voltages
- One referenced to primary ground
- One isolated from primary ground
- Less than 1% ripple on each output
