Working Principle

The operating principle of the MIC2800-GFMYML-TR device is based on a switching regulator topology, employing an internal power switch that is controlled by a pulse width modulation (PWM) signal. This PWM signal is generated by an internal voltage-mode control circuit, which provides excellent line and load regulation. It also features protection against input over-voltage, output over-voltage, output current limit, and output short circuit protections.

During normal operation, the internal control circuit senses the output voltage and adjusts the PWM signal to maintain the desired output voltage. The power switch turns on and off based on the PWM signal, allowing only a current through the switch that is determined by the input voltage, the output voltage, and the inductor. This current is the source current and is the sum of the output current and the inductor peak current. The switch turns off when the peak current reaches the current-limit threshold, and then the inductor energy is stored. When the voltage across the switch is at its minimum, the switch turns on again, releasing the stored energy in the inductor, and the cycle starts again.

When the input voltage rises above or falls below the regulation voltage level, or when the output current exceeds its rated value, the internal control circuit will take the necessary action to limit or regulate the output. This protection feature minimizes the damage to the connected load or power source due to sudden overvoltage or overcurrent.
