Working Principles
LTC4228IUFD-2#TRPBF operates by continuously monitoring the input voltage and comparing it to the configured overvoltage and undervoltage thresholds. If the input voltage exceeds the overvoltage threshold, the device triggers a fault condition and reports it through the FLT pin. Similarly, if the input voltage falls below the undervoltage threshold, a fault condition is triggered.
The power good indicator (PG) provides a signal indicating that the output voltage is within the desired range. The device also incorporates short-circuit protection and thermal shutdown features to prevent damage to the circuitry.
