KA3845B Overview
In the 8-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Qualified to work in a 0°C~70°C TA dc switcher. Switching can be done at Up to 500kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Through Hole. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 8 of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "KA3845". Switching converter has a total of 8 pins. A maximum voltage of 25V is accepted by the dc to dc regulator as an input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. Because of DC switcher's Through Hole, it is suitable for most prototype designs and applications. 500kHz is the maximum frequency of this dc regulators. In total, thare switch converters have 1 functions. It runs on a supply current of 17mA.
