TPS54424 Description
The TPS54424 is a full-featured 17-V (19-V maximum), 4-A synchronous step-down DC/DC converter in a 3.5 mm × 3.5 mm HotRod™ QFN package. The device is optimized for small solution size through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through peak current mode control, which reduces ponent count, and by selecting a high switching frequency, reducing the...
