UC3845D Overview
The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. For outputs of 1, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 12V~28V. Suitable for a 0°C~70°C TA dc switcher. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 14 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC3845". In total, switching converter has 14 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 13.5V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. A frequency of 500kHz is set for the switching controller. The dc switching utilizes 11mA when it is in a dormant state. Input voltage can be set to 25V for nominal working status. Current supplied to the controller should not exceed 25mA.
