The TPS65288RHAR from Texas Instruments is a highly integrated power management IC featuring three step-down buck converters. Designed for efficiency, it incorporates both high-side and low-side MOSFETs for fully synchronous conversion. The device supports a wide input supply voltage range of 4.5 V to 18 V, with adjustable output voltages down to 0.8 V.
Key electrical specifications include continuous output currents of 3 A for Buck1 and 2 A for Buck2 and Buck3, with peak currents reaching 3.5 A and 2.5 A respectively. The switching frequency is adjustable from 300 kHz to 2.2 MHz via an external resistor. The TPS65288RHAR also includes two USB power switches with current limiting, operating independently from the buck converters.
This component is housed in a compact, thermally efficient 40-pin 6-mm x 6-mm RHA (QFN) package, suitable for surface mounting. It operates within a junction temperature range of -40°C to 125°C. The device offers features like pulse skipping mode for high light-load efficiency, forced PWM mode, support for pre-biased outputs, and integrated protection mechanisms including cycle-by-cycle current limit and thermal shutdown.
The TPS65288RHAR is well-suited for multi-rail systems requiring sequenced power rails for processors, FPGAs, and peripherals, along with USB power delivery. Its programmability for soft-start and current limit, combined with integrated protection, helps reduce external component count.
