Product Overview
The TPS54560 is a Texas Instruments Power_Management step-down DC-DC converter designed around an internal high-side power MOSFET. The converter operates from a 4.5 to 60 V input range and provides step-down regulator capability up to 5 A. It also supports 65 V ISO 7637 load dump pulse survivability, making the device applicable to high-voltage input converter rails where transient tolerance is required by the extracted datasheet data.
Control and support pins include BOOT, VIN, EN, FB, COMP, SW, and RT/CLK. A bootstrap capacitor is required between BOOT and SW for the high-side MOSFET drive supply. EN can be pulled below 1.2 V to disable the device and may float to enable through the internal pull-up current source. FB is the inverting input of the gm error amplifier, while COMP connects external frequency compensation components.
The package is HSOP (8), 4.89 mm x 3.9 mm body, with PowerPAD. Recommended operation covers 0.8 to 58.8 V output voltage, 0 to 5 A output current, and -40 to 150 °C junction temperature.
