UC3844AD8G4 Product Details
UC3844AD8G4 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. A 10V~30V voltage is supplied to the dc control and used for operating it. Suitable for work in a 0°C~70°C TA dc switcher. With this switching controller, you can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 8 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "UC3844". Total pins of switching converter are 8. Particularly, switching converter is a type of Switching Regulator or Controllers. A 15V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. There is 450kHz frequency setting on the switching controller. It is possible to set the input voltage as 25V for nominal working statuses. Voltage 11V must be supplied. In order to ensure proper operation, the controller should not receive more current than 25mA.
