Working Principle

The MAX16055BAUB+T power management solution works by using an integrated regulator to maintain stable operation in the presence of line transients, current surges, and motor load transients. The integrated regulator consists of an adjustable fixed frequency oscillator, enable, low-duty cycle operation, undervoltage lockout, and an adjustable peak current limit. The adjustable voltage detection circuit helps to monitor line transients and currents, while the adjustable accuracy regulator helps to control output voltage. Furthermore, the device features over-temperature protection and a current limiting (CL) circuit for prevention from over-currents.

The MAX16055BAUB+T requires an external switch to control the output and typically operates in fixed frequency operation. The frequency is determined by the adjustable oscillator while the enable input allows the user to switch the output off when not required. The MAX16055BAUB+T includes an integrated low-duty cycle control circuit which helps reduce the power consumption during no-load or light-load conditions. The integrated under-voltage lockout allows the user to adjust the system’s threshold to prevent any output voltage below a pre-set limit.

The adjustable peak current limit helps to avoid over-currents by limiting the amount of current that can flow in given situations. The current limit is typically adjusted to provide protection from over-currents and transients. Furthermore, the MAX16055BAUB+T includes an over-temperature protection circuit to protect from thermal breakdowns and to automatically reduce power in dangerous situations.
