Texas Instruments TPS54527 / TPS54528 5A SWIFT™ Converters
Texas Instruments TPS54527 and TPS54528 5A synchronous step down (SWIFT™) converters are adaptive on-time D-CAP2™ mode synchronous buck converters. The TI TPS54527 and TPS54528 feature a wide input voltage range of 4.5V to 18V and an output voltage range of 0.76V to 6.0V. The D-CAP2 mode of these TI SWIFT converters enables fast transient response. The TI TPS54528 includes Eco-mode™ for high efficiency during lighter load conditions. The TI TPS54527 and TPS54528 are designed for use in a wide range of applications for low-voltage systems, including digital TV power supplies and Blu-ray™ players.
