Texas Instruments TPS563240 Synchronous Step-Down Voltage Regulators
Texas Instruments TPS563240 Synchronous Step-Down Voltage Regulators are optimized to operate with minimum external component counts and to achieve low standby currents. These simple and easy-to-use 3A synchronous step-down regulators employ D-CAP3™ mode control, providing fast transient response and supporting low ESR and output capacitors. The Texas Instruments TPS563240 voltage regulators operate in pulse skip mode that maintains high efficiency during the light load operation. With the implementation of Out-of-Audio™ (OOA) operation, these regulators maintain 25KHz frequency under light load conditions. Typical applications include TV, set-top boxes, broadband modem, access point networks, wireless routers, and surveillance.Features
