UC3526DWG4 Product Details
UC3526DWG4 Overview
In the SOIC package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. It can switch at 400kHz. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 18 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. There are 18 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 5V voltage based on test statistics. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 450kHz is set for the switching controller. You should keep dc regulator at 0°C degrees or higher. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. 1 functions (s) are included in the switch converters. Designing voltage regulators switchings with 18 pins. Switching can take place at a maximum frequency of 400kHz. It is possible to set the input voltage as 35V for nominal working statuses. This is an ideal solution for switching controllers with 100mA inputs. During normaloperations, it outputs a value of 13V. Voltage rating is 35V.
