Frequently Asked Questions
What is the maximum continuous output current of the TPS568215OARNNT, and which processor power rails can it support?
The TPS568215OARNNT delivers up to 8 A continuous output current, making it capable of powering core voltage rails of FPGAs such as Xilinx Artix-7 or Intel Cyclone 10 devices, DDR memory VTT rails at 0.6 V, and auxiliary 3.3 V rails simultaneously from a single 12 V bus input.
Over what input voltage range does the TPS568215OARNNT operate, and what output voltages are achievable?
The regulator operates from 4.5 V to 17 V input and produces an adjustable output from 0.6 V to 5.5 V, covering standard digital supply rails including 0.9 V, 1.0 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V using a simple external resistor divider network.
How does voltage-mode PWM control in the TPS568215OARNNT affect transient response versus current-mode controllers?
Voltage-mode control provides superior noise immunity and simpler compensation compared to current-mode, though it typically requires a Type-III compensation network. With an integrated compensation option in this device, designers achieve fast 50 µs to 100 µs transient settling times at 8 A step loads without external compensation components.
What switching frequency does the TPS568215OARNNT support, and how does that influence inductor selection?
The TPS568215OARNNT supports switching frequencies up to approximately 600 kHz, allowing the use of compact inductors in the 0.47 µH to 2.2 µH range with low DCR values around 1 mΩ to 5 mΩ, resulting in a high-efficiency, small-footprint point-of-load converter suitable for dense PCB designs.
