Introduction:

TPS60110PWP is a high efficiency synchronous DC-DC step-down power converter integrated with a high-side MOSFET, an inductor and an internal regulator that also includes a PMOS transistor. It has a wide input voltage from 2.6V to 5.5V and support up to 1.5A switch current. Its output voltage is specified for voltages down to 0.6V. The TPS60110PWP is designed for applications requiring up to 1.5A of continuous output current. This device is ideally suited for portable and battery-powered applications due to its small package size and integrated oscillator that requires no external components.

Application Fields:

The TPS60110PWP is most commonly used in consumer and portable electronics, such as smartphones, tablets, PDAs, and notebooks, but can also be used in other applications such as home appliances and industrial equipment. It is suitable for supplying CPUs and other processors, as well as providing power to memory and ASICs. Moreover, it can be used in low-power and low-noise applications that require high efficiency and precision, such as CD ROMs and DVD players.

Working Principles:

The TPS60110PWP synchronous dc-dc step-down power converter works by converting a higher input voltage to a lower regulated output voltage. The device integrates a high side low R DS(on) MOSFET and a low side MOSFET, as well as an inductor, back-bias P-MOSFET and an internal voltage regulator. The voltage regulator provides a constant output voltage. The integrated high side MOSFETs switch at fixed currents and uses the energy stored in the inductor to produce the regulated output.

The core of the converter is a voltage feedback loop that produces an error signal as the difference between the output voltage and a reference voltage. This error signal is used by the internal voltage regulator to regulate the output voltage by controlling the output current to match the desired output voltage. The higher the output voltage, the higher the current switch frequency. The device provides an ideal power saving solution with a high efficiency rate due to the low R DS(on) of the integrated MOSFETs.

Conclusion:

The TPS60110PWP synchronous dc-dc step-down power converter is a highly efficient and precise power converter, which is ideally suited for supplying portable channels, as well as providing power to memory and ASICs. This device contains a high side MOSFET and a low side MOSFET, as well as an inductor, back-bias P-MOSFET and an internal voltage regulator, allowing it to provide an efficient and precise output voltage with a high level of energy saving.
