UC3845ANG4 Overview


Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. 7.6V~30V is the supply voltage and the operating voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. The switching controller is capable of switching at the 500kHz position. The Through Hole allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 8. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "UC3845". Switching converter has a total of 8 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. As determined by the test statistics, the output voltage of DC regulator is 15V. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. Switching controllers operate at 450kHz frequencies. It is possible to set the input voltage as 25V for nominal working statuses. Switching controller is necessary to provide a voltage of 11V. Current supplied to the controller should not exceed 25mA.
