UC3844ADTRG4 Product Details
UC3844ADTRG4 Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 10V~30V voltage is supplied to the dc control and used for operating it. Qualified to work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 14. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Searching "UC3844" will return other relevant dc to dc converter ics. 14 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Based on the test statistics, DC regulator outputs voltage 15V. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. 450kHz is the frequency of the switching controller. 25V is the nominal working voltage. Voltage 11V must be supplied. There should be 25mA more than 25mA amps of current supplied to the controller.
