UC3825DW Overview
Capsuled in the 16-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. 2 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. 8.4V~30V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. In this switching controller, the switch can be set to 340kHz~460kHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Ramp, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. 16 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Searching "UC3825" will return other relevant dc to dc converter ics. Total pins of switching converter are 16. Specifically, switching converter falls under the Switching Regulator or Controllers category. dc dc voltage regulators should have a minimum input voltage of 8.8V. According to the test statistics, DC regulator outputs 13V voltage. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most. In most cases, the output current of the dc dc regulator will be 1.5A, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 85 %. 1MHz is the frequency of the switching controller. DC to DC voltage regulator has the value of CAN ALSO BE CONFIGURED IN CURRENT MODE to better satisfy the requirement. The supply voltage should be 15V. In order to ensure proper operation, the controller should not receive more current than 33mA.
