External Circuits

The TPS73527DRVR is designed to easily integrate into a variety of designs. It has a variety of external components that can be configured to match the application requirements. The external components include resistors, capacitors, inductors, diodes, and transistors. Each of these components carries out a specific function an allows the regulator to adjust the output voltage based on the input voltage.

Functional Overview

At the core of the TPS73527DRVR is a voltage regulator system that can be used to generate either step-up or step-down regulated voltages. This system is based on an IC containing an internal voltage reference, error amplifier, control logic, and power MOSFET. The voltage reference provides a constant voltage, which is compared by the error amplifier to the output of the feedback circuit. The feedback circuit is based on the external resistors and capacitors, which are connected in the form of a voltage divider. This voltage divider sets the voltage at the output of the circuit to the desired level.

The error amplifier then compares the output of the feedback circuit to the internal voltage reference. If the feedback voltage is lower than the reference voltage, then the error amplifier produces an output signal that causes the internal control logic to turn on the power MOSFET. This in turn increases the output voltage to the desired level. Conversely, if the feedback voltage is higher than the reference voltage, the error amplifier produces an output signal that causes the control logic to turn off the power MOSFET, which lowers the output voltage.

Applications

The TPS73527DRVR can be used in a variety of applications. It is especially useful for industrial applications that require precise voltage regulation over a wide range of temperatures. It is also used in consumer electronics to regulate the output voltage of battery-powered devices. It is commonly used in automotive applications to regulate the voltage from the alternator and to provide power to the ECU.
