What are the key features of TPS40091PWR?
- 4-channel multiphase architecture reduces output ripple and enables high-current delivery for CPU/ASIC power rails
- Current-mode PWM control with tri-state output for precise dynamic voltage regulation and fast transient response
- Wide input voltage range of 4.5 V to 15 V supports standard 5 V and 12 V bus designs
What is TPS40091PWR used for?
The TPS40091PWR is well-suited for high-current server and desktop CPU power delivery systems, where its 4-channel multiphase topology spreads thermal load across multiple phases and reduces bulk capacitance requirements. It also targets ASIC, FPGA, and DSP core voltage regulators operating from a 12 V input rail, providing tight voltage regulation under dynamic load transients. Networking and telecom infrastructure equipment designers use this controller to achieve compact, high-efficiency buck converters with simple current balancing.

Frequently Asked Questions
What input voltage range does the TPS40091PWR support?
The TPS40091PWR operates over an input voltage range of 4.5 V to 15 V, with a nominal operating point of 12 V. This range accommodates standard 5 V and 12 V bus architectures found in server, desktop, and industrial power designs.
How does the 4-channel multiphase design benefit high-current CPU power applications?
Using 4 interleaved phases at 90-degree offsets reduces the effective output ripple frequency by 4x, allowing smaller output capacitors while supplying currents exceeding 100 A to modern CPU cores. Each phase carries a fraction of the total load, lowering per-phase inductor current and improving overall thermal performance.
When is the TPS40091PWR a preferred alternative to a single-phase buck controller in ASIC power designs?
For ASICs demanding core currents above 30 A from a 12 V rail, the TPS40091PWR multiphase approach provides lower ripple and faster load-step response compared to a single-phase design. The 4-phase current-mode PWM control also simplifies PCB layout by distributing heat across 4 external MOSFETs rather than one large device.
What package does the TPS40091PWR use and how does it affect PCB layout?
The TPS40091PWR ships in a 20-pin TSSOP (PWR suffix) package, measuring approximately 6.5 mm x 4.4 mm. The small outline footprint allows placement close to the power stage MOSFETs, minimizing gate-drive trace inductance and supporting clean PCB routing for a 4-phase buck converter.
