The TPS53318 and TPS53319 devices are integrated MOSFET, 8A or 14A synchronous switches with D-CAP mode.

They are designed for ease of use, low external component count, and space-constrained power systems.

These devices feature an accurate 1%, 0.6V reference, and integrated boost switch.

Competitive features include: wide 1.5V to 22V conversion input voltage range, minimal external components, D-CAP™ for ultra-fast response

Mode control, automatic skip mode operation, internal soft-start control, selectable frequency and no compensation required.
