The TPS563207 is a single, adaptive on-time, D-CAP2™ mode, synchronous buck converter requiring a very 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 580 kHz and operates in Forced Continuous Conduction Mode (FCCM). The high-side and low-side switching MOSFETs are incorporated inside the TPS563207 package along with the gate-drive circuitry. The low drain-to-source on-resistance of the MOSFETs allows the TPS563207 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS563207 dc/dc synchronous converter is designed to provide up to a 3-A output from an input voltage source of 4.3 V to 17 V. The output voltage range is from 0.806 V to 7 V. Rated input voltage and output current ranges for the evaluation module are given in Section 2.
The TPS563207EVM evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 3 A from 4.3-V to 17-V input. This user’s guide describes the TPS563207EVM performance.
