TPS53355 datasheet


TPS53355 is a D-CAP mode, 30-A synchronous switcher with integrated MOSFETs. It is designed for ease of use, low external component count, and space-conscious power systems.

This device features 5 mΩ/2.0 mΩ integrated MOSFETs, accurate 1%, 0.6-V reference, and integrated boost switch. A sample of competitive features include: 1.5-V to 15-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.


1. 96% maximum efficiency

2. Conversion input voltage range : 1.5 V to 15 V

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

4. Output voltage range : 0.6 V to 5.5 V

5. 5-V LDO output

6. Supports single rail input

7. Integrated power MOSFETs with 30 A of continuous output current

8. Auto-skip Eco-mode for light-load efficiency
