TPS54680PWPRG4

The TPS54680PWPRG4 is a integrated power supply solution designed to reduce system complexity while enhancing efficiency. It is a high-performance, four-phase system PMIC (Power Management ICs) designed for asymmetric or symmetric buck converters used by low-power embedded or microcontroller-based applications. It provides a complete solution for point-of-load (PoL) powering, eliminating the need for discrete components. Additionally, its integrated PMBus compliant digital interface simplifies system control and management.

The TPS54680PWPRG4 application field includes a wide range of industries, from automotive, industrial and consumer to communications, computing and wired/wireless connectivity. It is a dynamic, highly efficient power supply for applications with power requirements ranging from dozens of milliwatts to several hundred watts.

The TPS54680PWPRG4 features a powerful programmable algorithm with Proportional-Integral (PI)-based control loops and leading-edge capabilities such as ActiveShunt, Active Surge, Disconnect, and Adaptive Maximum Duty Cycle (MDC). Its adaptive MDC enables fast transient response while operating near peak efficiency. The wide input voltage range allows the device to operate at either 12V or 24V inputs, simplifying the design of power supplies that are tolerant to both types of inputs. It also features two independent high-side and low-side gate-drivers with a minimum of four integrated MOSFET outputs. This configurable device is ideal for use in next-generation power architectures.

Working Principles

The TPS54680PWPRG4 works on the principle of regulating the input voltage to maintain a constant output voltage. It achieves this using its integrated voltage regulator, which uses a Proportional-Integral (PI) control loop to compare a set point voltage with the actual output voltage and adjust the gain of the loop accordingly to maintain a steady output voltage. Additionally, it has built-in digital communications and configurable output parameters, allowing for remote monitoring and management of the device. The on-chip diagnostic functions and SmartBoost patent pending feature give the TPS54680PWPRG4 an edge in providing a complete power solution.

The TPS54680PWPRG4 also features a wide input voltage range, allowing it to regulate an input voltage of between 24V and 48V. This allows it to be used in a variety of systems and makes it suitable for use in applications that require multiple supplies with different input voltage ranges. Additionally, the device has an integrated programmable protection circuit, allowing it to provide against current, temperature, and other faults.

The TPS54680PWPRG4 includes Fast-Loop Control, ActiveShunt, Active Surge, and Adaptive Maximum Duty Cycle (MDC), which enables fast transient response and operation near peak efficiency. It also features a Power-on Reset (POR) circuit and an internal soft-start with an adjustable startup time, allowing the device to be safely started with minimal inrush current. Finally, the TPS54680PWPRG4 is an 4-phase system PMIC, and it features dual high-side and low-side gate-drivers with a minimum of four integrated MOSFET outputs.

The TPS54680PWPRG4 is a highly efficient and powerful programmable integrated power solution for a wide range of applications. It is a complete and comprehensive solution for point-of-load (PoL) power requirements, offering flexibility and improved performance for low-power embedded or microcontroller-based systems. With its wide input voltage range, adaptive MDC, and configurable output parameters, the TPS54680PWPRG4 is an ideal choice for next-generation power architectures.
