Isolated 3-W Automotive Bias Regulator Reference Design (Flyback Topology)
Description
This reference design is for an input voltage range from 6V to 18V and is able to handle surge up to 40V. The output voltage is 12V with 250mA maximum output current. This reference design needs no opto-isolator due to primary side regulation and therefore no aging trouble of the opto-isolator.
Features
- Cost effective due to boost controller TPS40210Additional undervoltage lockout prevents large input currentsSmall transformer due to discontinuous modeFine dynamic behaviorWell-suited for high temperature environment due to low temperature riseThe reference design is built and tested
