UC3825Q Overview

As a result of 20-LCC (J-Lead) compact design, the switching controller is compatible with most applications. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 8.4V~30V. Suitable for a 0°C~70°C TA dc switcher. There is a switch at 340kHz~460kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a QUAD terminal on the switching converters. A variety of dc switching's functions can be performed on 20 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "UC3825". There are 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 8.8V. As determined by the test statistics, the output voltage of DC regulator is 13V. A maximum voltage of 30V is accepted by the dc to dc regulator as an input voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. The switching controller works at a frequency of 1MHz. DC to DC voltage regulator has the value of CAN ALSO BE CONFIGURED IN CURRENT MODE to better satisfy the requirement. The nominal supply current for this the controllers dc is 33mA.
