TPS565208EVM-858: 1.05V @ 5A, 4.5 ~ 17V in

Summary

The TPS565208EVM-858 evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 5 A from 4.5-V to 17-V input The TPS565208 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 550 kHz. The high-side and low-side switching MOSFETs are incorporated inside the TPS565208 package along with the gate-drive circuitry.

The low drain-to-source on resistance of the MOSFETs allows the TPS565208 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS565208 dc/dc synchronous converter is designed to provide up to a 5-A output from an input voltage source of 4.5 V to 17 V. The output voltage range is from 0.760 V to 7 V. Rated input voltage and output current ranges for the evaluation module are given in Table 1.
