+description: |
+ The PF5300, PF5301, and PF5302 integrate high-performance buck converters,
+ 12 A, 8 A, and 15 A, respectively, to power high-end automotive and industrial
+ processors. With adaptive voltage positioning and a high-bandwidth loop, they
+ offer transient regulation to minimize capacitor requirements.
