The TPS53317RGBT special purpose voltage regulator is an advanced synchronous regulation solution providing excellent efficiency and accuracy in small form-factor applications.
The TPS53317RGBT provides efficient and accurate step-down conversion from an output voltage of 5 V to 1 V. It features a 2.2-MHz switching frequency, allowing for a small external solution size. This voltage regulator is designed to support applications requiring high-accuracy, low-output-voltage regulation. It also offers excellent load and line transient response and can support fast current-limit look-up-table updates for enhanced system protection. The device is capable of sinking up to 1 A of current and has a low quiescent current of 105 μA/MHz, making it ideal for use in battery-powered systems.
The device is powered by a 3.2-V to 5.5-V input voltage, and it has an adjustable output voltage range of 0.8 V to 1.15 V. It also has an adjustable switching frequency of between 200 kHz and 2.2 MHz, selectable via external compensation components. The device has a slew-controlled power-good (PG) output that guarantees a precise settling time. The TPS53317RGBT includes several features to facilitate system integration, such as an adjustable soft-start, high-side and low-side current limit and precise current limit ripple. It also features an input voltage compensation and over temperature protection.
The TPS53317RGBT utilizes a high-frequency monolithic synchronous buck switching regulator that operates from a 3.2-V to 5.5-V input voltage, and it provides a regulated output voltage of 0.8 V to 1.15 V. It uses two internal 5.9-V NMOS FETs. A current mode control architecture allows the device to provide fast transient response and excellent noise rejection. A current sharing feature enables an increase in output current limit at light loads, thus allowing the device to operate with a fixed compensation network.
The TPS53317RGBT integrates an internal synchronous rectifier which improves the light-load efficiency and reduces the external components count. The device also features a slew-controlled power good (PG) output which guarantees a precise settling time. In order to provide increased system protection, current limiting can be set to one of thirty-two points through an external register.
The TPS53317RGBT provides excellent efficiency and low quiescent current, making it ideal for use in battery-powered systems. It is also capable of providing the ideal voltage regulation for high-accuracy, low-output-voltage regulation applications. Its adjustable switching frequency enables the solution size to be kept small while still maintaining excellent efficiency. Additionally, its slew-controlled power-good (PG) output guarantees a precise settling time.
In conclusion, the TPS53317RGBT is a high-performance and adjustable step-down voltage regulation solution. It provides excellent efficiency and accuracy, while also offering high-side and low-side current limit and precise current limit ripple. With its adjustable switching frequency, it is perfect for applications requiring a small form-factor. Its slew-controlled power-good (PG) output guarantee a precise settling time, and its current sharing feature enables an increase in output current limit at light loads, thus allowing the device to operate with a fixed compensation network.
