+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.
