UC2845ANG4 Overview
With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. Packaged in solid enclosures, this pmic has a Tube rating. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Suitable for work in a -40°C~85°C TA dc switcher. dc dc regulator is made easier with Through Hole. Frequency Control is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of 8 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2845". There are only 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. Statistically, DC regulator outputs 15V volts. You should note that the dc dc regulator's usual output current is 200mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 500kHz is set for the switching controller. Input voltage can be set to 25V for nominal working status. The supply voltage should be 11V. In order to ensure proper operation, the controller should not receive more current than 25mA. An input of 11mA current flow could satisfy the operation of the switching converter .
