This device is part of TI’s extensive portfolio of power management solutions and the optimal choice for solutions requiring greater than 6V output adjustable voltage levels.

Application Field

The TPS78628DCQ can be used in a variety of applications that require stable voltage outputs with a wide input voltage range and low power consumption. Some applications include automotive electronics, communications systems, industrial systems, as well as battery powered products.The TPS78628DCQ is suitable for any applications where high performance and low power are essential, such as portable medical devices, mobile phones, wearable devices and IoT applications.

Working Principle

The TPS78628DCQ uses a linear voltage-regulator topology, where a transistor is used to regulate the current flow through a load. The transistor is basically a switch, which can be opened or closed. If the transistor is closed, current will flow freely from the output of the voltage-regulator to the load. If the transistor is open, no current will flow from the output to the load. The current flow is controlled by adjusting the position of the transistor relative to the input and output voltage.

The TPS78628DCQ uses an adjustable output voltage of up to 6V, which is regulated by the output voltage feedback pin. A comparator is employed to sense the output voltage and actuate the transistor. The voltage output is adjusted via an external resistor divider connected to the output voltage feedback pin. The TPS78628DCQ also features input voltage protection, reverse-current protection, as well as current-limit and thermal-shutdown protection.

Conclusion

In summary, the TPS78628DCQ is an integrated, high-performance voltage regulator PMIC from Texas Instruments. It is designed to deliver exceptional power efficiency and offers excellent selectivity, low noise and fast transient-response capability. It can be used in a variety of applications such as automotive electronics, communications systems, industrial systems and battery powered products. The TPS78628DCQ uses an adjustable output voltage of up to 6V, which is regulated by the output voltage feedback pin.
