UC3525BDWG4 Overview


In the 16-SOIC (0.295, 7.50mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 8V~35V volts and has 8V~35V supply voltage. Worked in an dc switcher with a 0°C~70°C TA rating. Switching can be done at 100Hz~400kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Dead Time Control, Frequency Control, Ramp, Soft Start is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 16 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 20V. You can find other relevant dc to dc converter ics by searching "UC3525". There are only 16 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. DC regulator outputs 18V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 100mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. A frequency of 450kHz is set for the switching controller. You can set the input voltage to 35V for nominal working status.
