InnoSwitch3-TN ICs incorporate all feedback components while supporting isolated, non-isolated, single and multi-output designs for the most compact, flexible auxiliary power supply solution.”\n\nThe advanced InnoSwitch3-TN flyback controller delivers constant efficiency across the load range and less than 5 mW no-load consumption. The flexibility afforded by FluxLink™ communication technology means that positive and negative outputs are easily achieved. InnoSwitch3-TN ICs can be used in a 5 V single-output power supply, with two positive output rails, or with both positive and negative rails, without any external feedback components. Safety-rated FluxLink technology also ensures reliable synchronous rectification and accurate constant voltage and constant current on the output. The low forward drop of the SR MOSFET also ensures excellent cross-regulation performance. Comprehensive safety features include output over-current and over-temperature protection. The small MinSOP package and low number of external components required for a full PSU design make the InnoSwitch...
