SCM1209A 9-24V Transformer Driver for Isolated Power Supplies Features        Packaging Push-Pull Driver for Small Transformers Two built-in power MOSFET and Simple application circuit Limited MOSFET current at start-up Output short circuit protection and over temperature protection with self-recovery function Under voltage protection Meet 9~24V input 3.3-24V output 1-3W applications 220uF-4000uF capacitive load Application Optional Packaging of Product: TSOT-23-6, please refer to “Ordering Information” for details of silk screen.    Isolated Interface Power Supply for CAN, RS-485, RS-232 DC-DC Isolation Converter Distributed generation resources Function Description The SCM1209A is a raw side push-pull controller designed specifically for small form factor isolated power supplies in isolated interface applications. Simply match a simple peripheral circuit to achieve 9-24V input, 3.3-24V output, power 1-3W isolated power supply. The chip consists of an oscillator, two drivers and two power switching tubes, each driver controlling the current flow of one winding on the primary side. Each way includes a power NMOS tube, and the two alternating drives achieve the push pull control of the original side. The internal logic ensures the first open and then close operation between the two power tube switches. In addition, the SCM1209A also integrates a variety of protection functions such as undervoltage and overtemperature to ensure the reliability of the converter. Its soft starting feature can prevent the large current impact during the machine starting process; The design of short circuit timing and current limiting drive decouple the capacitive load capacity from the short circuit protection capacity. Adjust the short-circuit protection threshold according to the input voltage and temperature, so that the consistency of the capacitive load and short-circuit protection is good, and is not affected by the input and temperature.
