Quality Control: Learn More
Texas Instruments UC3572N is a flyback DC-DC controller designed for negative output voltage applications. This 8-PDIP packaged component operates as a step-up/step-down regulator with a maximum duty cycle of 92%. Key control features include current limiting and ramp compensation, facilitating stable operation at switching frequencies up to 100kHz. The UC3572N is suitable for through-hole mounting and accepts supply voltages ranging from 4.75V to 30V. It functions as a transistor driver for the output stage. This controller is commonly utilized in power supply designs for industrial and consumer electronics.
