DESCRIPTION

The SP6650 Evaluation Board is designed to help the user evaluate the performance of the SP6650 for use as a single Li-Ion battery input to +5V output DC-DC Converter. The SP6650 operates from 2.7V to 6.5V input, with the highest efficiency in the range 3.0V to 4.2V where the Li-Ion battery has the most energy. The SP6650UEB evaluation board is a complete power supply circuit to provide ease of evaluation for the DC/DC Converter performance.

■ High efficiency synchronous stepdown converter with up to 95 efficiency

■ Ideal for cellular telephones, wireless modems, PDAs, digital cameras

■ Programmable inductor peak current limit, 2.7V-6.5V input voltage range

■ MSOP package & SMT components for small, low profile power supply

■ Easy evaluation for different distributed power systems and batterypowered portable equipment
