Explanation

IR3621 integrated circuit combines dual synchronous antihypertensive control and drive, providing economic high -performance high -performance and flexible solutions. IR3621 generates two independent output voltage or current as a large current application shared single output in the two -phase mode. No. 180! Different phase operation allows reduction in input and output capacitors. Other key features include two independent programming soft startup functions, allowing system -level sorting output voltage in different configurations. When the pre -deflection voltage protection function prevents the output voltage and when there is a pre -existing voltage at the output end, the load may be damaged during the startup process. The frequency of each phase switch can be as high as 500kHz, which allows flexibly adjusting the operation of IC to meet the system -level requirements and simplify the design of the system -level filter. Protective functions, such as optional short -circuit or atresia current restrictions and under pressure to provide locks to provide the required system -level security failure.
