UC3525BNG4 Overview


This switching controller fits most application requirements since it is packaged in a PDIP package. dc motor controller is suitable for 2 output generation. The switching controller is capable of switching at the 400kHz position. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of terminations with 16 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 20V. In total, switching converter has 16 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, the DC regulator outputs 5.1V voltage. 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 used by the switching controller. Temperatures should be kept at 0°C or higher. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. Total number of functions (s) for thare switch converters are 1. There is a design for voltage regulators switching with 16 pins. There is a maximum frequency of 400kHz that the controller can switch at. For nominal working status, the input voltage can be set as 35V. This is an ideal solution for switching controllers with 100mA inputs. When it is working normally, it outputs a value of 18V. Switching voltage regulators is rated 35V in terms of maximum supply voltage.
