Universal Line Power Supply for PLC using PSR Flyback and Compact DC/DC Stages Reference Design
Texas Instruments
Description
The PMP9185 reference design uses the UCC28710 primary-side regulated flyback controller to generate a 15V output from a univeral AC input with maximum 20W output power followied by DC/DC and LDO stages using TPS54229 and TPS650250: and 5V: 3.3V: 1.8V and 1.2V are provided.
