UC3845DTR Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 12V~28V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. The switching controller is capable of switching at the 500kHz position. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. 14 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "UC3845" to find other relevant dc to dc converter ics. Pins number 14 of switching converter in total. Specifically, switching converter falls under the Switching Regulator or Controllers category. Statistically, the DC regulator outputs 13.5V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers work at 450kHz Hz. A nominal working status is achieved when the input voltage is set to 25V. It is not recommended to supply more current to the controller than 25mA.
