3 Description
The TPS53355 is a D-CAP™ mode, 30-A synchronous switcher with integrated MOSFETs. It is designed for ease of use, low external ponent count, and space-conscious power systems.
This device features
5-mΩ/2-mΩ integrated MOSFETs, accurate 1% 0.6-V reference, and integrated boost switch. A sample of petitive features include: 1.5-V to 15-V wide conversion input voltage range, very low external ponent count, DCAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control, selectable frequency, and no need for pensation.
