UC3526DWTR Overview
With its 18-SOIC (0.295, 7.50mm Width) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. Voltages 8V~35V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with 0°C~70°C TA. This switching controller can switch at 1Hz~400kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Reset, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Various 18 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics can be found by searching "UC3526". The switching converter has a total of 18 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, DC regulator outputs 13V volts. You should note that the dc dc regulator's usual output current is 100mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controller operates at 450kHz Hz. 35V is the nominal working voltage.
