Working Principles

The MIC3230YTSE is a voltage regulator that takes an input voltage within the range of 4.5V to 28V and provides a regulated output voltage between 1.25V and 26V. It utilizes a control loop to maintain the desired output voltage by adjusting the duty cycle of an internal switching transistor.

When the enable pin (EN) is set high, the device starts operating and regulates the output voltage based on the feedback received from the FB pin. The soft-start feature gradually ramps up the output voltage during startup to prevent excessive inrush current.

The MIC3230YTSE also incorporates protection mechanisms such as overcurrent and thermal shutdown to safeguard against potential faults or excessive temperature.
