UC2847DW Overview
As a result of 16-SOIC (0.295, 7.50mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). 6.95V~40V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -40°C~85°C TA. It can switch at 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Soft Start which allows efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . 16 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. Based on the test statistics, DC regulator outputs voltage 5.1V. The dc to dc regulator is limited to 40V input voltage. 0.5A is the largest value switching converter outputs.
