Texas Instruments TPS565201/TPS565208 Step-Down Voltage Regulators
Texas Instruments TPS565201/TPS565208 Step-Down Voltage Regulators are simple, easy-to-use, 5A synchronous step-down converters. These devices are optimized to operate with minimum external component counts and achieve low standby currents. These switch mode power supply (SMPS) devices employ D-CAP2™ control, which provides a fast transient response and requires no external compensation components. D-CAP2 also allows the use of low-equivalent series resistance (ESR) specialty polymer capacitors and ceramic output capacitors. The Texas Instruments TPS565201 operates in pulse skip mode, maintaining high efficiency during a light load operation.
