SG2845DM Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). 7.6V~30V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -25°C~85°C TA. The switching controller can be switched at 1Hz~500kHz. A generalization of dc dc regulator can be made using Surface Mount. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. 8 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. SG*845 can be used to locate other relevant dc to dc converter ics. There are 8 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 13.5V voltage according to the test statistics. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. There is 500kHz frequency setting on the switching controller. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 30V. In dormant mode, 11mA is used.
