These devices contain four internal DC-DC Buck converters, controlled by a PIN select switch. The following sections will discuss the application fields and working principles of the TPS65123RGTG4.

Applications

The TPS65123RGTG4 is a DC-DC converter dip switch IC, and its application fields include battery-powered mobile phones, digital cameras and other devices. This component\'s Buck converter can provide high accuracy and fast transient response. Therefore, it is suitable for battery powered mobile devices where the power supply can vary and where the power switch must run at low noise levels.

The device\'s internal 8-channel p-channel MOSFETs provide a low Rbbd capacitance characteristic and a low Rds low Dropout operation. The low output current and the active delay functions minimize the glitch noise from the channel outputs. All of this makes the TPS65123RGTG4 an ideal component for mobile phones with battery-powered, high-efficiency applications.

Working Principle

The TPS65123RGTG4 is a 8-channel stepdown DC-DC converter dip switch IC with voltage range 0.6 V to 5.5 V.

The working principle of the TPS65123RGTG4 is based on the Buck converter. It takes an input voltage and outputs a lower voltage, equivalent to the difference between the input and output voltages. In addition, the TPS65123RGTG4 is also equipped with an integrated switching controller and an on-board logic circuit. When an input voltage is applied, the logic circuit detects it and enables the Buck converter. The Buck converter switches the input voltage by using the integrated switching controller.

The TPS65123RGTG4 includes four internal DC-DC Buck converters, each of them controlled by a separate PIN select switch. When a switch is enabled, the corresponding converter can step down the input voltage according to the logic circuit, achieving a lower output voltage.

Conclusion

The TPS65123RGTG4 is an 8-channel stepdown DC-DC converter dip switch IC with voltage range 0.6 V to 5.5 V. It offers advantages such as high output current up to 1 A, low noise and fast transient response. These features make the TPS65123RGTG4 a suitable power management device for low power and low voltage applications such as smartphones, tablets and DSCs.
