Overview
The TPS61030PWPR from Texas Instruments is a highly efficient synchronous boost converter designed to provide a stable output voltage from a variety of input sources. This device is particularly suited for products powered by one-cell Li-Ion or Li-polymer batteries, as well as two to three-cell alkaline, NiCd, or NiMH batteries. It offers high efficiency power conversion, capable of delivering output currents up to 1 A at 5 V from an input voltage as low as 1.8 V. The converter uses a fixed frequency, pulse-width-modulation (PWM) controller with a synchronous rectifier to achieve maximum efficiency.
