Description
General part information
TPS54424 Series
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 component count, and by selecting a high switching frequency, reducing the inductor footprint.
The peak current mode control simplifies the loop compensation and provides fast transient response. Cycle-by-cycle peak current limiting on the high-side and low-side sourcing current limit protects the device in overload situations. Hiccup limits MOSFET power dissipation if a short circuit or over loading fault persists.
