Voltage regulation is a process of changing the voltage to a level that is suitable for a given application. It is very important in power supply design by allowing the system to utilize a single external power source with multiple required output levels. The Texas Instruments TPS62067DSGR DC-DC Switching Regulator helps achieve this by providing the capability to step down and/or boost voltage, depending on the need of the system.

The TPS62067DSGR is a synchronous buck-boost switching regulator with an extremely efficient, 2-A, adjustable output voltage (0.6~5V). It features an input source from a single-cell Li-Ion, multiple cell Alkaline and Ni-MH batteries, or any other DC source, which makes it suitable for a wide range of power supply design applications. In addition, the small, low profile 8-pin package and low quiescent current of 1.2 μA make this regulator the ideal component for mobile or other low power applications.

Application Field

The TPS62067DSGR switching regulator is an ideal component for several portable device applications. Examples include notebook/desktop PCs, point-of-sale (POS) terminals, and wireless systems.This component also works well in amplifiers, video cameras, projected TV, and media players. In addition, due to its adjustable output voltage, this component can be used in a wide variety of portable applications.

Working Principle

The TPS62067DSGR works in a buck-boost configuration using two internally synchronous, switch-mode power transistors to convert and regulate input power (VIN) to the desired output (VOUT). When the input voltage is higher than the output voltage, the component operates in buck mode and the high-side switch is on. When the input voltage is lower than the output voltage, the component operates in boost mode and the low-side switch is on. The TPS62067DSGR also features two additional control circuitry for protection against input overvoltage and overtemperature.

Conclusion

The Texas Instruments TPS62067DSGR is a very efficient, adjustable DC-DC switching regulator suitable for a wide range of power supply design applications. With its adjustable output voltage and extremely low quiescent current, this part makes it the ideal component for mobile or other low power applications. Its synchronous buck-boost switching configuration and wide range of control circuitry allow it to deliver accurate, reliable and safe power conversion.
