Working Principles

The UC2706NG4 is a voltage mode PWM controller used in power management applications. It regulates the output voltage by comparing it with a reference voltage and adjusting the duty cycle of the power switch accordingly. The error amplifier provides precise regulation, while the internal compensation network ensures stability. The soft-start feature gradually ramps up the output voltage during startup, preventing excessive current flow. The under-voltage lockout and over-voltage protection safeguard the circuit from potential damage.
