One of the most important components of a power management system is the voltage regulator. The voltage regulator is used to provide a reliable and consistent voltage to various components of the system. The TPS60123PWP is a low cost, high efficiency DC-DC switching regulator specifically designed for use in low power applications. The device can generate supply rails from 1.5V to 5.5V from a wide input voltage range of 2.5V to 18V.

Overview of the TPS60123PWP

The TPS60123PWP is a DC-DC switching regulator IC designed with an integrated, high-efficiency, low-noise buck converter. The switching frequency is adjustable from 200kHz to 1MHz with a voltage different between the input and the output rail, up to a maximum of 9V. The switching frequency can be programmed by an external resistive divider. The device has two internally regulated high-side output pins, each with up to 130 mA of current available. The device is available in either a QFN package or a thermally enhanced WQFN package.

Applications of the TPS60123PWP

The TPS60123PWP is well-suited for a variety of applications. Its adjustable switching frequency and efficient design make it ideal for long-term battery-powered applications because it can help to minimize the amount of power consumed. The device is also well-suited for other low power, low noise applications such as modems, IoT devices, and wearables. Additionally, the wide input voltage range and the integrated inductor allow the device to be used in a variety of applications, from simple 5V/3.3V powering to more complex systems.

Working Principle of the TPS60123PWP

The working principle of the TPS60123PWP is based on a buck switching regulator. The device utilizes a high-side NMOS switch and an integrated inductor to convert a higher input voltage to a lower output voltage. The switching happens at a frequency of 200kHz to 1MHz, depending on the resistor divider. When the switch is on, current moves through the inductor and an equal current flows through the load. This results in an increase in the inductor’s current, which then stores the energy in the form of a magnetic field. When the switch is turned off, the current flow through the inductor decreases and the stored energy is released and supplied to the output. This energy is used to maintain the voltage at the output. This process is repeated at a constant frequency, resulting in a smooth and regulated output voltage.

Conclusion

In conclusion, the TPS60123PWP is a low cost, high efficiency DC-DC switching regulator specifically designed for use in low power applications. The device is well-suited for a variety of applications, such as those requiring long-term battery power and low noise. The device can generate supply rails from 1.5V to 5.5V from a wide input voltage range of 2.5V to 18V. The working principle of the device is based on a buck switching regulator, where a high-side NMOS switch and an integrated inductor are used to convert the higher input voltage to a lower output voltage.
