Texas Instruments TPS56x219 Synchronous Step-Down Regulators are simple, easy-to-use, 2A or 3A synchronous step-down converters in 8 pin SOT-23 package. Each device is optimized to operate with minimum external component counts and achieve low standby current. These switch mode power supply (SMPS) devices employ D-CAP2™ mode control providing a fast transient response. Each device supports both low equivalent series resistance (ESR) output capacitors and ultra-low ESR ceramic capacitors with no external compensation components. The devices operate in continuous conduction mode, which reduces the output ripple voltage in light load compared to discontinuous conduction mode.
