TPS53318 datasheet



The TPS53318 and TPS53319 are D-CAP mode, 8-A or 14-A synchronous switchers with integrated MOSFETs. They are designed for ease of use, low external component count, and space-conscious power systems.

These devices feature accurate 1%, 0.6-V reference, and integrated boost switch. A sample of competitive features include: 1.5-V to 22-V wide conversion input voltage range, very low external component count, DCAP mode control for super fast transient, auto-skip mode operation, internal soft-start control, selectable frequency, and no need for compensation.

The conversion input voltage ranges from 1.5 V to 22 V, the supply voltage range is from 4.5 V to 25 V, and the output voltage range is from 0.6 V to 5.5 V. These devices are available in 5 mm x 6 mm, 22-pin QFN package and is specified from –40°C to 85°C.


1. Conversion input voltage range : 1.5 V to 22 V

2. VDD input voltage range : 4.5 V to 25 V

3. 91% efficiency from 12 V to 1.5 V at 14 A

4. Output voltage range : 0.6 V to 5.5 V

5. 5-V LDO output

6. Supports single-rail input
