UC3845NG4 Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. For 1 outputs, the dc motor controller is appropriate. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). 12V~28V is the operating voltage and supply voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. A switching controller such as this can switch at a value of 500kHz . dc dc regulator can be generalized using Through Hole. Switching control is made easier with the dcdc regulator's Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC3845". There are a total of 8 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, the DC regulator outputs 5.1V voltage. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controller operates at 450kHz Hz. It is possible to set the input voltage to 25V for nominal working status. A controller's current should not exceed 25mA. Input of 11mA current flow would satisfy the operation requirements of the switching converter .
