UC3844ADM Overview


With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control operates at 10V~30V and has a 10V~30V supply voltage. Worked in a 0°C~70°C TA dc switcher before. The switching controller is capable of switching at the Up to 500kHz position. The Surface Mount allows it to be used for dc dc regulator in general. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of terminations with 8 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. UC*84 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 8. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 5V voltage based on test statistics. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. Switching controller operates at 500kHz Hz. As long as the dc switching is in a dormant state, it utilizes 11mA. There is 11mA supply current for it.
