It offers linear and switching regulation in a single package, thus making it an efficient and cost-effective solution for power supply design. This article looks into the application fields and working principle of TPS65235-1RUKR devices.

Application Fields

TPS65235-1RUKR devices are used in applications that require a high level of flexibility, as they can deliver a variety of voltages and currents. They are capable of providing multi-channel, regulated voltages down to 0.6V. In addition, they can operate on input voltages ranging from 1.8V up to 5.5V. This makes them suitable for powering a wide variety of medical and consumer electronics applications, such as medical sensors, wearable devices, and handheld games consoles.

They are also ideal for applications requiring very low power designs, as they are capable of delivering a low quiescent current of 6.8 µA. This makes them an ideal choice for applications where battery life is a priority.

The TPS65235-1RUKR devices support both linear and switching regulation modes, which makes them suitable for a wide range of applications. They offer excellent noise suppression and transient response, making them a great choice for powering sensitive loads. Furthermore, their high efficiency rating (up to 94%) makes them an excellent choice for applications where power consumption is a concern.

Working Principle

TPS65235-1RUKR devices use a combination of linear and switching regulation to provide a variable output voltage. In linear regulation, an error amplifier compares the actual output voltage to the desired output voltage. If the actual output voltage is greater than the desired output voltage, the error amplifier increases the voltage on the power transistor, reducing the output voltage. Conversely, if the actual output voltage is lower than the desired output voltage, the error amplifier decreases the voltage on the power transistor, increasing the output voltage.

In the switching regulation mode, a Pulse Width Modulated (PWM) controller compares the voltage feedback signal to the desired output voltage. When the voltage feedback signal is greater than the desired output voltage, the PWM controller turns the power transistor off for a period of time. Conversely, if the voltage feedback signal is lower than the desired output voltage, the PWM controller turns the power transistor on for a period of time.

By combining the two regulation modes, the TPS65235-1RUKR devices can offer an efficient and reliable power supply with little noise and low power consumption. They also offer a low output impedance and a temperature range of -40°C to 125°C.

Conclusion

The TPS65235-1RUKR devices are a versatile family of multi-output regulated power supply ICs that offer excellent performance and low power consumption. They are suitable for a wide range of applications, including medical devices and consumer electronics, where battery life and power consumption are key considerations. Furthermore, they offer both linear and switching regulation, allowing them to handle a wide range of load and input voltages.
