Working Principle

The TPS60240DGKT is a DC-DC step down switching regulator, which uses a switching circuit to regulate the output voltage. The device operates in four stages, converting the incoming DC voltage to an output voltage that is equal to the input voltage minus the switching losses.In the first stage, the device detects the input voltage and then switches the internal power switch at a frequency determined by an external clock generator or external resistor divider network.In the second stage, the energy stored in the inductor is passed to the output capacitor and reduces the voltage ripple.In the third stage, the error amplifier measures the output voltage and adjusts the power switch duty cycle as required, to maintain a constant output voltage.In the fourth stage, the device senses the output current and adjusts the output voltage through pulse skipping or pulse frequency modulation to avoid overloading the output.The TPS60240DGKT features over current and overvoltage protection to prevent damage to the device and other components in the system. It also features thermal protection to prevent damage due to overheating.

Conclusion

The TPS60240DGKT is a DC-DC step down switching regulator and PMIC from Texas Instruments, designed to meet automotive requirements. It is an ideal power management solution for automotive, industrial and consumer applications, such as audio systems, LED lighting, home appliances, charging ports, and embedded systems.
