UC3525BDWTR Overview


It comes in the 16-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. For 2 outputs, the dc motor controller is appropriate. There is a Tape & Reel (TR) solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 8V~35V. Qualified to work in an dc switcher with 0°C~70°C TA. There is a switch at 100Hz~400kHz that can be used with this controller. A generalization of dc dc regulator can be made using Surface Mount. Dead Time Control, Frequency Control, Ramp, Soft Start provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . An array of 16 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 20V volts. UC3525 can be used to locate other relevant dc to dc converter ics. 16 pins are present on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, DC regulator outputs 18V volts. A starting point for a project is to note down the dc dc regulator's usual output current, which is 100mA. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. Switching controllers operate at 450kHz frequencies. Input voltage can be set to 35V for nominal working status.
