SG2845M Overview
It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. For outputs of 1, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. A 7.6V~30V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where -25°C~85°C TA is the -25°C~85°C TArm. In this switching controller, the switch can be set to 1Hz~500kHz. dc dc regulator is made easier with Through Hole. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . 8 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. In addition to "SG*845", there are other relevant dc to dc converter ics you can find. Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. The dc to dc regulator can only accept a maximum input voltage of 25V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. Because of DC switcher's Through Hole, it is suitable for most prototype designs and applications. Switching controllers operate at 500kHz frequencies. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. During dormancy, the dc switching uses 11mA.
