What are the key features of this regulator?

Key features include a wide 4V-24V input range, 8A output capability, 600kHz pseudo-constant frequency, programmable valley current limit, and integrated 20mΩ/10mΩ switches.

What should engineers consider during PCB design?

Engineers should ensure wide copper traces for power paths, place input/output capacitors close to the IC, and use a four-layer PCB with adequate thermal vias for the exposed pad.

What protection features are included?

The device includes cycle-by-cycle current limit, input UVLO, internal soft-start, output under-voltage protection (hic-cup mode), over-voltage protection, and thermal shutdown.
