Description

General part information

TPS54 Series

The TPS54A24 is a full-featured 17-V, 10-A synchronous step-down DC/DC converter in a standard 4 mm × 4 mm WQFN 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.
