UC1844AMDREP Product Details
UC1844AMDREP Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 10V~30V and has a 10V~30V supply voltage. Worked in a -55°C~125°C TA dc switcher before. In this switching controller, the switch can be set to Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 8 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC1844" will return other relevant dc to dc converter ics. 8 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. 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. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controllers work at 500kHz Hz. DC switching uses 11mA when it is dormant. In order to ensure the dc switcher's functionality, users must limit the voltage to 25V due to the dc switcher's maximum input voltage. DC switchers cannot produce output currents greater than 200mA. Datasheets state the switching converter can output up to 15V volts. For operation, the switching converter could be satisfied with 11mA current flow input.
