UC2843AQ Overview
In the 20-LCC (J-Lead) package, the switching controller meets most application requirements. For outputs of 1, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). 7.6V~30V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~125°C TJ. In this switching controller, the switch can be set to Up to 500kHz. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the QUAD position. The 20 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. It is recommended that the input voltage of the dc dc voltage regulator be 8.2V. The dc to dc regulator can only accept 25V input voltage. A maximum value of 1A is output for current.
