Texas Instruments TPS564201EVM-801
The TPS564201 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 high-side and low-side switching MOSFETs are incorporated inside the TPS564201 package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allows the TPS564201 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS564201 DC/DC synchronous converter is designed to provide up to a 4-A output from an input voltage source of 4.5 V to 17 V. The output voltage range is from 0.8 V to 6.5 V. The TPS564201EVM-801 evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 4 A from 4.5-V to 17-V input. This user’s guide describes the TPS564201EVM-801 performance.
