Working Principles

The ICE3AR2280JGXUMA1 operates on the principle of pulse width modulation (PWM). It regulates the output voltage by adjusting the duty cycle of the switching signal. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle accordingly. The current sense pin (CS) provides feedback for current regulation.

When the input voltage exceeds the desired output voltage, the over-voltage protection feature activates and reduces the duty cycle to maintain a stable output. Similarly, the over-current protection feature limits the duty cycle when the load current exceeds the set limit.
