Texas Instruments Relays - I/O Relay Modules TPS53647RTAT

The TPS53647 is a 4-phase, D-CAP+ step-down controller with non-volatile memory and PMBus interface, designed for high-current point-of-load applications such as ASIC power in servers and communications equipment. It is housed in a 40-pin QFN package measuring 6.00 mm × 6.00 mm and operates over a temperature range of -40°C to 125°C. The device supports output voltages from 0.5 V to 2.5 V in 5-mV steps, input voltages from 4.5 V to 17 V, and switching frequencies from 300 kHz to 1 MHz. It features dynamic phase shedding, phase current imbalance detection, and programmable overcurrent protection with 16 levels. Compatible with NexFET power stages like the CSD95372BQ5MC, the controller enables efficient high-frequency operation without external drivers and supports pre-bias startup. Configuration can be set via pinstraps or PMBus and stored in NVM to reduce external components.
