Maxim MAX8815A 1A DC-DC Step-Up Converter

Maxim MAX8815A 1A DC-DC Step-Up Converter

The Maxim MAX8815A 1A DC-DC Step-Up Converter is a high-efficiency, low quiescent current (30µA), synchronous step-up converter with True Shutdown™ and inrush-current limiting. The Maxim MAX8815A DC-DC Step-Up Converter generates any output voltage from 3.3V to 5V from a 2-cell NiMH/NiCd or a single-cell Li+/Li polymer battery. The MAX8815A has a preset 2.5A current limit, allowing 500mA load at 1.8V input and 1A load at 2.5V input when the output is set to 5V. The Maxim MAX8815 is ideal for use in a variety of applications, including DSC and DVC, microprocessor / DSP core power, cell phones, PDAs, MP3 Players, and more.
