Frequently Asked Questions
What is the maximum output current of TPS548D22RVFT and which load applications require this level?
TPS548D22RVFT delivers up to 40 A continuous output current from a 1.5 V to 16 V input supply. This current level targets high-performance FPGAs, multi-core processors, and high-end ASICs in server and networking boards, where core voltages of 0.8 V to 1.8 V at 20 A to 40 A are common, and transient response must settle within microseconds.
How does the differential remote sense feature on TPS548D22RVFT improve voltage regulation accuracy?
TPS548D22RVFT uses two dedicated SENSE+ and SENSE- pins connected directly at the load point rather than at the converter output capacitor. This compensates for resistive drops across PCB traces carrying 40 A, which can introduce 50 mV to 200 mV of error. Differential remote sense maintains regulated output within ±1% of setpoint at the actual load, critical for processors with tight tolerance windows.
Can TPS548D22RVFT operate from a 5 V input bus as well as a 12 V bus?
Yes, TPS548D22RVFT supports an input voltage range of 1.5 V to 16 V, so it operates from both 5 V and 12 V input rails. At 5 V input with a 1.0 V output and 40 A load, the converter achieves high efficiency using its integrated MOSFETs. Designers must verify that the 40 A output limit and the duty cycle at 5 V input are within the switching frequency budget set by the external resistor.
