TPS25741RSMT is an advanced power management Integrated Circuit (PMIC) that is specialized for boosting and bucking applications. It is well suited for applications such as mobile and other battery-powered products, white-goods, and other light-load switches. In this article, I will discuss the application field as well as the working principle of TPS25741RSMT.

Application Field

One of the key applications of TPS25741RSMT power PMIC is in battery-powered applications where the input voltage is prone to a wide range of variations. The TPS25741RSMT can detect the input voltage and work accordingly to adjust the output voltage to maintain the desired level. Due to its high efficiency, it can achieve up to 0.6A at a voltage up to 5.5V. This makes it well suited for applications such as voltage level adjustments, audio DAC interfaces, mixed-signal power supply regulation, and many other applications. Due to its low quiescent current and wide voltage range, the TPS25741RSMT consumes low amount of power, making it well suited for battery-powered devices. In addition, the device also offers unique features such as adjustable output voltage, variable on-time, power-saving shutdown modes and programmable current limit.

Working Principle

In order to understand the working principle of TPS25741RSMT, let us first look at a basic DC-DC boost converter. In a DC-DC boost converter, the input voltage is converted to a higher voltage level at the output. This is done by increasing the frequency of pulses or switching the circuit periodically. It is this process which is used by TPS25741RSMT to boost the voltage from the input to the output.

TPS25741RSMT is an advanced switching device which increases the output voltage through a combination of two stages: The Boost Stage and the Buck Stage. In the Boost Stage, the current is increased by increasing the frequency of pulses. This increases the voltage in the Boost Stage and the output voltage is then directly proportional to the input voltage. The second stage is the Buck Stage, which reduces the current in order to control the output voltage level.

The TPS25741RSMT also has a number of additional features such as adjustable output voltage, variable on-time and shutdown modes which can be used to reduce power consumption and extend the life of the device. In addition, it also has an integrated current limit and overvoltage protection. This helps to protect the device and other components from unexpected voltage spikes and other abnormal conditions.

Conclusion

In conclusion, the TPS25741RSMT power PMIC is an advanced dual-stage IC device specialized for boosting and bucking applications. It is well suited for applications such as mobile and other battery-powered products, white-goods and other light-load switches. The TPS25741RSMT offers unique features such as adjustable output voltage, variable on-time, power-saving shutdown modes and programmable current limit, making it ideal for a wide variety of applications.
