Overview
The TPS63000DRCR from Texas Instruments is a high-efficiency single-inductor buck-boost converter designed to provide a versatile power supply solution for a variety of battery-powered devices. This converter is suitable for products powered by two-cell or three-cell alkaline, NiCd, or NiMH batteries, as well as single-cell Li-ion or Li-polymer batteries. It features a fixed frequency, pulse width modulation (PWM) controller with synchronous rectification, ensuring maximum efficiency across a wide range of load currents.
The device operates over a free air temperature range of –40°C to 85°C and is packaged in a compact 3-mm × 3-mm 10-pin VSON package (QFN), making it ideal for space-constrained applications.
