UC2845N General Description
The UC2845N is a high-performance voltage mode controller for switching power supplies. It is designed to operate in a wide range of applications, including telecom, industrial, and consumer electronics. The device features a precision reference voltage of 5V, which helps maintain accurate regulation of the output voltage. The UC2845N offers a programmable oscillator frequency that can be adjusted externally, allowing for flexibility in tuning the switching frequency to optimize system performance. It also includes a current sense input for cycle-by-cycle current limiting, overcurrent protection, and a soft-start function to prevent excessive inrush current.With a wide supply voltage range of 7V to 30V, the UC2845N can be used in various power supply configurations. It is housed in an 8-pin PDIP package, making it easy to integrate into existing circuit designs.
