Frequently Asked Questions
What input voltage range does TPS40021PWP support?
TPS40021PWP operates over a 2.25 V to 5.5 V input voltage range, with a nominal input of 5 V. This wide range makes it suitable for single-supply 3.3 V or 5 V bus step-down converter designs across industrial and telecom applications.
How does TPS40021PWP implement PWM control for a buck converter?
TPS40021PWP uses voltage-mode pulse width modulation, comparing a sawtooth ramp against the error amplifier output to set the duty cycle. This approach provides predictable loop response and simplifies compensation across load currents in regulated 5 V step-down applications.
Which package does TPS40021PWP use, and how does it affect PCB design?
TPS40021PWP is housed in a 16-pin HTSSOP package, which occupies minimal PCB area while providing adequate thermal dissipation. The small outline footprint allows high-density layouts for space-constrained server and networking boards needing compact DC/DC controller placement.
When would TPS40021PWP be preferred over a fully integrated buck converter?
TPS40021PWP suits designs above 3 A output where external FETs with lower RDS(on) reduce conduction losses compared to integrated solutions. Using external components also allows optimization for efficiency targets at specific switching frequencies between 50 kHz and 1 MHz.
