Texas Instruments TPS562202S 2A ECO-Mode Synchronous Buck Converter

Texas Instruments TPS562202S 2A ECO-Mode Synchronous Buck Converter is optimized to operate with minimum external components and also optimized to achieve low standby current. This switch-mode power supply (SMPS) device employs D-CAP2 mode control providing a fast transient response. It also supports both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. The Texas Instruments TPS562202S operates in ECO mode, which maintains high efficiency during a light load operation. The TPS562202S is available in a 6-pin 1.6mm × 1.6mm SOT563 (DRL) package and specified from a –40°C to 125°C junction temperature.
