Working Principles

The ICE2A765I is a PWM controller designed for switched-mode power supplies. It operates by modulating the width of the output pulses to control the power delivered to the load. The feedback pin (FB) compares the output voltage with a reference voltage, and the error amplifier adjusts the duty cycle accordingly to maintain stable regulation. The current sense input (CS) provides information about the load current, enabling overload protection. The soft-start function gradually increases the duty cycle during startup to prevent excessive inrush current.
