Description for the TPS56300

The high performance TPS56300 synchronous-buck regulator provides two supply voltages to power the core and I/O of digital signal processors, such as the ‘C6000 family. The ripple regulator, using hysteretic control with droop compensation, is configured for the core voltage and features fast transient response time reducing output bulk capacitance.

The LDO controller drives an external N-channel power MOSFET and functions as an LDO regulator, suitable for powering the I/O or as a power distribution switch. To promote better system reliability during power up, voltage sequencing and protection are controlled such that the core and I/O power up together with the same slow-start voltage. At power down, the LDO and ripple regulator are discharged towards ground for added protection. The TPS56300 also includes inhibit, slowstart, and under-voltage lockout features to aide in controlling power sequencing. A tri-level voltage identification network (VID) sets both regulated voltages to any of 9 preset voltage pairs from 1.3 V to 3.3 V. Other voltages are possible by implementing an external voltage divider. Strong MOSFET drivers, with a typical peak current rating of 2-A sink and source are included on chip, enabling high system currents beyond 30 A. The high-side driver features a floating bootstrap driver with the internal bootstrap synchronous rectifier. Many protection features are incorporated within the device to ensure better system integrity. An open-drain output POWER GOOD status circuit monitors both output voltages, and is pulled low if either output fall below the threshold. An over current shutdown circuit protects the high-side power MOSFET against short-to-ground faults at load or the phase node, while over voltage protection turns off the output drivers and LDO controller if either output exceeds its threshold. Under voltage protection turns off the high-side and low-side MOSFET drivers and the LDO controller if either output is 25% below VREF. Lossless current-sensing is done by detecting the drain-source voltage drop across the high-side power MOSFET while it is conducting. The TPS56300 is fully compliant with TI DSP power requirements such as the ‘C6000 family.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
