illustrate

The LM2694 step of the switching regulator is required to implement all the functions of a low cost, high efficiency, buck bias regulator that provides a load capacity of 0.6A. This buck regulator contains an N-channel buck switch and is available in a 3×3 thermally enhanced LLP-10 package and TSSOP-14 package. The program provides feedback regulation, eliminates the need for loop compensation for fast load transient response, results, and simplifies circuit design. The operating frequency remains dependent on the line and load due to the inverse relationship between input voltage and on-time. Smooth transition in the valley, from current limit current limit detection results in constant current constant voltage mode, reducing frequency and output voltage without foldback. Other features include VCC undervoltage lockout, overtemperature shutdown, gate drive undervoltage lockout, and maximum duty cycle limit.
