Frequently Asked Questions
What input voltage range does TPS40020PWPG4 support, and what output voltage can it regulate to?
The TPS40020PWPG4 accepts an input voltage from 2.25 V to 5.5 V, making it suitable for 3.3 V and 5 V bus applications. The output voltage is programmable via an external resistor divider down to 0.7 V reference, enabling core voltage regulation for DSPs, FPGAs, and microprocessors requiring sub-1 V rails from standard logic supply rails.
How does the programmable switching frequency of TPS40020PWPG4 affect power supply component sizing?
The TPS40020PWPG4 supports a programmable switching frequency up to 1 MHz set by an external resistor. At 1 MHz, the required output inductor value drops to approximately 1 µH to 4.7 µH and output capacitors can be reduced by 50% compared to 300 kHz designs, enabling smaller passive components and a more compact power module footprint.
For a 3.3 V to 1.0 V point-of-load converter on an FPGA board, why choose TPS40020PWPG4 over a simple linear regulator?
The TPS40020PWPG4 achieves typical efficiency above 90% for a 3.3 V to 1.0 V conversion, versus approximately 30% efficiency for a linear regulator at the same voltages. This 60% efficiency improvement reduces power dissipation and heat sink requirements significantly in FPGA applications drawing 3 A to 10 A on the core rail, lowering thermal design complexity.
