The device provides a fast line and load transient response, enabling its use for applications requiring low output voltage deviation during load transients. Additionally, it improves system power efficiency by combining the functions of a buck converter and a boost converter into a single IC.

Working Principle of TPS76825QPWPRQ1

The operation of the TPS76825QPWPRQ1 is based on a synchronous buck-boost switching topology, which allows it to smoothly transition between different operating modes. Under no-load (open loop) conditions, the device operates in one of its three working modes, depending on the input voltage. When the input voltage is above the output voltage, the device operates in buck mode, where the MOSFETs on the high side and low side are turned ON to maintain the output voltage. For input voltages below the output voltage, the device switches to a tie-point boost mode, with both the high side and the low side MOSFETs turning on simultaneously. Finally, for input voltages between the upper and lower tie-points, the device operates in buck-boost mode, where both the high side and the low side MOSFETs are turned on and off to maintain the output voltage.

The device also integrates power-path management, which allows it to seamlessly transition between the different operating modes. It features a low quiescent current of 6µA in shutdown, very fast line and load transient response, and adjustable current limit and differential remote sense. Additionally, it offers a high-accuracy output voltage and adjustable frequency from 600 kHz to 1.2 MHz. With its wide range of features and benefits, the TPS76825QPWPRQ1 is ideal for powering various applications with stringent output voltage requirements.
