Texas Instruments TPS56x210 Step-Down Voltage Regulators
Texas Instruments TPS56x210/TPS56x210A Synchronous Step-Down Voltage Regulators are simple, easy-to-use, 2A or 3A synchronous step-down converters in 8 pin SOT-23 packages. These devices are optimized to operate with minimum external component counts and to achieve low standby current. Each of these switch mode power supply (SMPS) devices employ D-CAP2™ mode control providing a fast transient response. They support both low equivalent series resistance (ESR) output capacitors such as speciality polymer and ultra-low ESR ceramic capacitors with no external compensation components. These devices operate in Advanced Eco-mode™, which maintains high efficiency during light load operation.
