The SD4947 is a DC-DC converter control chip for buck switching power supplies, driving external MOSFETs. The SD4947 features integrated high-voltage supply for fast startup, adaptive frequency reduction to further optimize conversion efficiency under light load conditions, and built-in frequency dithering to optimize EMI. The SD4947 also integrates various abnormal state protection functions, including: cycle-by-cycle peak current protection, VDD overvoltage protection, undervoltage protection, output overload protection, output overvoltage protection, and overtemperature protection. |SD4947TR|SD4947TR DATASHEET|SD4947TR IN STOCK|SD4947TR SILAN|SD4947TR RESELLER IN INDIA|SD4947TR RESELLER IN MUMBAI|SILAN DISTRIBUTOR IN INDIA|SILAN DISTRIBUTOR IN MUMBAI|SILAN DISTRIBUTOR NEAR ME|
