The TPS65257RHAR from Texas Instruments is a power management IC featuring three integrated synchronous step-down buck converters. This device is designed for high efficiency and simplified application design, allowing designers to optimize performance for various target applications.
Key electrical specifications include a wide input supply voltage range from 4.5 V to 16 V, with support for pre-biased outputs. The converters provide continuous loading of 3 A for Buck1 and 2 A for Buck2 and Buck3, with adjustable output voltage capabilities. The switching frequency can be set externally between 300 kHz and 2.2 MHz.
This IC is housed in a compact and thermally efficient 40-pin VQFN package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). The TPS65257RHAR includes features like a power good supervisor, reset generator, and a 1-A USB power switch with overcurrent and thermal protection, making it a versatile solution for power management needs.
