UC3525AQTRG3 Overview


The switching controller fits in the 20-LCC (J-Lead) package and is ideal for most applications. The dc motor controller is adquate to generate for 2 outputs. There is a Tape & Reel (TR) solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 8V~35V. Suitable for work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at 100Hz~400kHz. The Surface Mount value makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminals (s) are designed at QUAD. 20 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 20V volts. UC3525 can be used to locate other relevant dc to dc converter ics. 20 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 18V. It's important to remember that the dc dc regulator's normaloutput current is 100mA, so you should note it down when starting a new project. Voltage regulator dc to dc is designed to operate at 49 % duty cycle during power-ups and power-downs to ensure reliability. DC switcher's Surface Mount qualifies it for most applications and prototypes. Switching controller operates at 450kHz Hz. Users should apply 35V to operate the voltage regulator dc to dc safely and reliably. Input voltage can be set to 35V for nominal working status.
