SCM1703A Description
Please see “Ordering Information” for details The SCM1703A controller for isolated flyback power supply designs provides a voltage control using an opto-coupler feedback to improve transient response time to large load steps. Current control is acplished through Primary Side Regulation (PSR) techniques. This device processes information from opto-coupler feedback and an auxiliary flyback winding for precise...
