DC–DC converters are electronic switches for transferring electrical power from a low voltage source to a higher voltage. The TPS82698SIPT DC–DC converter, an integrated circuit manufactured by Texas Instruments, is a low-dropout step-up switching regulator. It can be used in a range of applications, ranging from low power to high power applications.

The typical application of TPS82698SIPT is for step up the voltage form the input power source, such as Li battery, to a higher level (around 5.5V typically). This chip is designed for space saving and delivers up to 90% efficiency. It is capable of delivering up to 600mA, and it supports a wide range of input voltages – from 2.2V to 5.5V, allowing the output voltage to be adjusted along the complete range from 2.2V up to 5.5V.

The TPS82698SIPT is a constant-voltage and constant-current power supply IC, ideal for automotive and consumer electronics applications. The device uses a buck-boost buck converter topology which allows the devices to step-up or down the output voltage as needed. Its efficiency remains high (>90%) across the full load range, with the low quiescent current (25 µA typ.) and low shutdown current, make it suitable for battery powered applications.

The TPS82698SIPT DC–DC converter has several advanced features which make it suitable for a wide range of applications. It supports load disconnect mode which allows the device to draw zero current during the off state and helps to reduce the power consumption of the circuit, while still keeping the output voltage at the desired level. In addition, the device supports a soft-start feature which prevents inrush current and allows capacitive loads to be safely connected. Its constant-currency feature helps maintains the required current level across a wide range of load conditions.

The TPS82698SIPT DC–DC converter has a wide range of features which make it suitable for a wide range of applications. Its low-dropout step-up switching regulator topology and advanced features make it ideal for low power to high power applications. Its load disconnect mode and soft-start feature ensure that it is highly efficient and reliable in delivery of power. Furthermore, its constant-currency feature provides consistent current across a wide range of load conditions, making it suitable for a variety of applications.
