TPS51610IRHBT application field and working principle

A precision voltage regulator typically serves as an interface between sensitive and non-sensitive loads. It ensures a stable output voltage at all times, no matter the input voltage or output load. The TPS51610IRHBT extended-range voltage regulator provides a typical output voltage of 1.8 V to 5 V, with very high accuracy (±1%).

Designed to replace legacy two-phase step-down converters, the TPS51610IRHBT is optimized to minimize output voltage ripple and reduce power loss. In addition, the device provides full fusion operation with a current limit of 10 A. This allows the device to be used in high current, high efficiency applications, such as powering FPGAs, core voltage regulators, and other applications requiring low output ripple and fast transient response.

The TPS51610IRHBT has a wide input voltage range from 4.5 to 36 V. This makes the device ideal for high voltage supplies, such as automotive applications, or higher input voltage systems that require a wide dynamic range. The device also offers fast transient response, with a frequency up to 2.25 MHz and a 0.8 V/µs threshold. In addition, the TPS51610IRHBT has an integrated overcurrent and overtemperature protection, as well as a power good indicator.

Application Fields

The TPS51610IRHBT is the ideal choice for a wide range of applications, such as powering core regulators in FPGAs, servers, high-end storage applications and other high current, high efficiency applications. The extended input voltage range and fast transient response make this an ideal solution for automotive, high voltage and system applications. It can also be used in industrial, embedded and portable applications.

Working Principle

The TPS51610IRHBT is an extended-range voltage regulator. The device is composed of two stages: a linear regulator and a switching regulator. The first stage is a linear regulator, which is used to regulate the output voltage. The linear regulator operates by sensing the load current and adjusting the output voltage accordingly. At low loads, the linear regulator is used to regulate the output voltage. At higher loads, the linear regulator is bypassed, and the switching regulator is used to regulate the output voltage. The switching regulator operates by converting the input voltage to various discrete output voltages. It measures the load current and adjusts the switching frequency as needed to maintain the output voltage.

The TPS51610IRHBT also includes an integrated overcurrent and overtemperature protection, as well as a power good indicator. This helps protect the device and the circuit from damage caused by short circuits or overtemperature conditions. In addition, the device offers a wide input voltage range of 4.5 V to 36 V and fast transient response, allowing it to be used in high voltage supplies, such as automotive applications.

Conclusion

The extended-range voltage regulator TPS51610IRHBT has a wide input voltage range and fast transient response, making it suitable for automotive, high voltage, system, and other power applications. The integrated overcurrent and overtemperature protection, as well as a power good indicator, ensures maximum safety and reliability. The device is an excellent choice for powering FPGAs, core voltage regulators, and other high current, high efficiency applications.
