UC3844AD Overview

As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) are supported. 10V~30V is the operating voltage and supply voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. It can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. 14 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Searching "UC3844" will return other relevant dc to dc converter ics. The switching converter has a total of 14 pins. The type is a particular Switching Regulator or Controllers of switching converter. The test statistics indicate that DC regulator outputs a voltage of 15V. You should note down the dc dc regulator's usual output current of 200mA when you start a project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 450kHz is set for the switching controller. In a dormant state, the dc switching uses 11mA. For nominal working status, the input voltage can be set as 25V. There is a requirement for a 11V supply voltage. It is important that the controller is supplied with 25mA more than 25mA volts of current. An input flow rate of 11mA could satisfy the switching converter 's operation requirements.
