Introduction to TPS630241YFFR

TPS630241YFFR is a high-efficiency step-down DC-to-DC converter that is designed to convert a higher voltage (or a fluctuating voltage) to a lower regulated output voltage with low quiescent current. The TPS630241YFFR is part of the Texas Instruments’ Power Management IC (PMIC) portfolio and is classified as a DC DC Switching Regulator.

Application Field of TPS630241YFFR

The TPS630241YFFR is ideal for use in space-constrained portable applications that require low output current and low quiescent current such as medical devices, wearables and hand-held devices. It is suitable for application in smartphones, tablets, digital cameras, and other portable audio devices. The device can also be used in automotive and industrial applications.

Features of TPS630241YFFR

The TPS630241YFFR offers several features that make it an ideal choice for energy-efficient power management applications. It has a wide input voltage range from 2.25 V to 6 V and an adjustable fixed output voltage range from 0.6 V to 5 V. It also offers a high-efficiency boost conversion with an operating frequency of 1.2 MHz.The device has an integrated low-dropout regulator (LDO) with Intelligent Power-Path Manager (IPP) that can deliver up to 1.5 A of input current. The device also features internal compensation, overvoltage protection, current limiting, thermal shutdown and other protection functions.

Working Principle of TPS630241YFFR

The TPS630241YFFR functions as a step-down DC-to-DC converter with an adjustable output voltage and low quiescent current. The high-efficiency boost conversion is achieved by using two transistors connected in a buck-boost topology.When the input voltage is greater than the output voltage, the two transistors act as a buck converter and step down the input voltage. When the input voltage is lower than the output voltage, the two transistors act as a boost converter and step up the input voltage. The output voltage is set with an external resistor divider connected across the output pin.The integrated low-dropout regulator (LDO) provides power to the internal control circuit, while the internal current-mode control circuitry regulates the output voltage. The integrated overvoltage protection feature ensures that the output voltage does not exceed a predetermined limit. The thermal shutdown and current-limiting features protect the device against over current and over temperature conditions.

Conclusion

TPS630241YFFR is a high-efficiency step-down DC-to-DC converter from Texas Instruments’ Power Management IC (PMIC) portfolio, classified as a DC DC Switching Regulator. The device is ideal for use in applications that require low output current and low quiescent current and is suitable for application in smartphones, tablets, digital cameras, and other portable audio devices. It features a wide input voltage range, adjustable fixed output voltage range, high-efficiency boost conversion, low-dropout regulator (LDO) with Intelligent Power-Path Manager (IPP), overvoltage protection, current limiting and other protection functions.
