The TPS56628 is a single, adaptive on-time, D-CAP2™ mode, synchronous buck converter requiring a low external component count. The D-CAP2 control circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 650 kHz. Pulse skipping Eco-mode™ operation improves efficiency under light load conditions. The high-side and low-side switching MOSFETs are incorporated inside the TPS56628 package along with the gate-drive circuitry. The low drain-to-source on-resistance of the MOSFETs allows the TPS56628 to achieve high efficiencies and helps keep the junction temperature low at high-output currents. The TPS56628 dc/dc synchronous converter is designed to provide up to a 6-A output from an input voltage source of 4.5 V to 18 V. The output voltage range is from 0.76 to 5.5 V. The TPS56628EVM-534 evaluation module circuit is a single, synchronous buck converter providing 1.05V at 6 A, from 4.5-V to 18-V input.
