LX2206 EVALUATION BOARD USER GUIDE INTRODUCTION TO PRODUCT The LX2206 Evaluation Board is available from Microsemi for evaluating the performance of the LX2206 Battery Charger integrated circuit. The component sizes used on the evaluation board facilitate easy probing, however, in practice, smaller component sizes are recommended to minimize the circuit physical size. KEY FEATURES Two independent programmable charge currents 0.5% Float voltage tolerance Charging up to 1A.
