UC3846Q Overview
This switching controller fits most application requirements since it is packaged in a 20-LCC (J-Lead) package. 2 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 6.95V~40V voltage is supplied to the dc control and used for operating it. Suitable for a 0°C~70°C TA dc switcher. There is a switch at 500kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . A variety of terminations with 20 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "UC3846". Pins number 20 of switching converter in total. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 13.5V voltage according to the test statistics. normally, the dc dc regulator's output current is 500mA, which you should keep in mind when starting a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. 450kHz is the frequency of the switching controller. 15V is the nominal working voltage.
