UC3526DWG4 Overview


This switching controller fits most application requirements since it is packaged in a SOIC package. It is sufficient to generate 2 outputs with this dc motor controller. Using this switching controller, it is possible to switch at 400kHz. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 18 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. In total, switching converter has 18 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 5V. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. A frequency of 450kHz is set for the switching controller. Keep dc regulator at a temperature of 0°C or above. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. 1 functions are available in total for the switch converters. Designing voltage regulators switchings with 18 pins. There is a maximum frequency of 400kHz that the controller can switch at. It is possible to set the input voltage as 35V for nominal working statuses. It is ideal for switching controllers with 100mA input. This process outputs a value of 13V for normalworking processes. Voltage rating is 35V.
