Introduction

AI Translation

The TPS51317 is a fully integrated synchronous buck regulator featuring D-CAP+™ mode architecture. This device is designed for space-constrained 3.3 V and 5 V buck systems requiring high performance and optimized component count. It supports input and conversion voltages up to 6.0 V, with an adjustable output voltage range of 0.6 V to 2.0 V. Housed in a 3.5 mm × 4 mm 20-pin QFN package (RoHS-compliant, lead-free), it operates across a wide temperature range of -40°C to 85°C.

Features
