The TPS54614MPWPREP is a synchronous DC-DC buck power stage controller designed to solve the complexity of High Voltage DC Power-conversion. It provides an integrated control solution that includes an input voltage regulator, gate drive, and gate-drive current regulator in a single IC. The TPS54614MPWPREP is a programmable solution for synchronous buck converters with up to 35A of output current. The device is ideal for applications that require high efficiency, small size and improved thermal performance.

The TPS54614MPWPREP belongs to the DCDC switching regulator category for PMIC Voltage Regulators. This kind of voltage regulator is popular for applications ranging from low-power LED lighting to high-performance industrial applications, as it provides a flexible, efficient, and cost-effective way of regulating power.

The TPS54614MPWPREP operates in an active-clamp forward topology with an integrated control mechanism and efficient power stage. Its boost-function minimizes the core voltage drop and eliminates the need for loss compensation at the input side. It offers many programmable features such as Output Voltage, Switching Frequency, Soft-start and Voltage Tracking.

The device employs active current-mode control together with an internal upper and lower voltage reference, both programmable via an external voltage. The maximum output current is controlled by applying an external current limit. The on-chip programmable soft-start mutes voltage transients, enabling a smooth start-up.

Since the drive is external and the control loop is internal, the TPS54614MPWPREP is able to operate with a wide range of device types. In addition, the device offers several protection features, such as Over-Voltage, Over-Temperature, and Under-Voltage, which are monitored and can trigger a fault signal in case of an abnormally high output voltage, overheating or low input voltage, respectively. These protection features make the regulator a highly reliable and safe solution, reducing the external components count and simplifying the design.

The main benefit of using the TPS54614MPWPREP is its high-performance, fast transient response and high efficiency, which makes it an ideal solution for a wide range of power supply applications, such as embedded systems, digital ICs, peripherals, and gaming consoles.
