Texas Instruments  TPS563209EVM-652

The TPS563209 is a simple, easy-to-use, wide-Vin, 3A synchronous step-down converter. The TPS563209 employs D-CAP2™ mode control that provides a fast transient response and support both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. TPS563209 operates in forced CCM, which maintains constant frequency during light load operation. The TPS563209EVM-652 operates from an input voltage range of 4.5 to 17 V and supplies a 1.05 V output voltage at up to 3 A load current
