Working Principle of TPS71750DSET

The TPS71750DSET uses a combination of linear regulators and PMIC circuitry to regulate a specific output voltage. At its most basic, the linear regulator portion of the PMIC takes a high input voltage and reduces it, using an internal resistive network and zerotherm compensation circuit. The voltage is further regulated by an internal error amplifier, which uses feedback from an external voltage divider to achieve regulation. The current limit on the device is set by an internal current-sense amplifier, which monitors the output current in order to limit it to the desired level.

The PMIC portion of the device uses a combination of control logic and control voltage generation circuitry to manage the internal power supply rails. The control logic receives inputs from the external input voltage and the output voltage, allowing the PMIC to detect when a fault condition has occurred and shut down the device. The control voltage generation circuitry generates the necessary control voltages to set the output voltage and power up or down the device in a controlled manner.
