UC1845AMDREP Overview


This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. This dc motor controller can be used to generate outputs with 1 numbers. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 7.6V~30V. Workable in an dc switcher where -55°C~125°C TA is the -55°C~125°C TArm. This switching controller can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of dc switching's functions can be performed on 8 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 15V volts. In addition to "UC1845", there are other relevant dc to dc converter ics you can find. 8 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. Switching controller operates at 500kHz Hz. In order to limit the voltage of a dc switcher whose maximum input voltage is 25V, it must be limited by the user. DC switcher will not be able to provide an output current above 200mA volts. Depending on the datasheet, the switching converter can output 15V volts at its peak. The switching converter could be operated with an input of 11mA current flow.
