TPS79925YZUR is an advanced linear regulator that provides up to 25V output voltage range and up to 1.5A continuous output current capability. It takes an input voltage of 3V to 34V, and can provide a wide selection of output voltages and current limits. The device features configurable error flags and delay, enabling system monitoring and protection features.

TPS79925YZUR is designed for the following application fields:

• Telecom equipment and power control
• Servers, data storage and other computing equipment
• Portable electronics such as cell phones, GPS equipment and digital media

The working principle of TPS79925YZUR is based on a high-speed transient voltage regulator. When the input voltage changes quickly, the device quickly adjusts the output voltage to keep the output voltage stable. The device uses a high-performance feedback loop and an advanced control architecture to provide superior dynamic performance over a wide range of input and output conditions, while minimizing the output voltage deviation. The device also features a buck-boost regulator, which is used to control the output voltage when the input voltage exceeds the maximum regulated voltage.

TPS79925YZUR utilizes two internal error amplifiers, a 5V reference and a filtered error amplifier path. The error amplifiers monitor both the output voltage and the error voltage, which reflects the difference between the programmed output voltage and the regulated output voltage. The 5V reference provides the reference voltage for the error amplifiers voltage loop control circuit. When there is an error voltage between the programmed output voltage and the regulated output voltage, the error amplifiers output the error signals which pulse width modulated (PWM) to control the upper and lower outputs of the buck-boost regulator.

The output of the buck-boost regulator is used to regulate the output voltage of the device. The output voltage of the device is controlled by the combined action of the upper and lower output stages. When the output voltage is above the preset level, the upper output switch is driven with a high duty cycle, while the lower output switch is driven with a low duty cycle. Conversely, when the output voltage is below the preset level, the lower output switch is driven with a high duty cycle, while the upper output switch is driven with a low duty cycle. This alternating action of the upper and lower outputs helps to stabilize the output voltage, while preventing overshoot and undershoot.

TPS79925YZUR also features various configurable error flags, including over-temperature, under-voltage and over-current, that can be used to prevent device damage. The delay feature provides the system with additional time to respond to errors before shutdown. The device also features a programmable soft-start time which can be used to reduce the inrush current during system power-up and power-down.

TPS79925YZUR is an advanced linear regulator suitable for a wide range of applications requiring small output voltage and current regulation. Its wide input voltage range, configurable error flags and delay, and precise output voltage regulation make it an ideal choice for power control in a wide range of applications.
