Product Summary
The MAX1566ETL+T provides a complete powersupply solution for digital cameras. MAX1566ETL+T improves performance, component count, and size compared to conventional multichannel controllers in 2-cell AA, 1-cell lithium-ion (Li+), and dual-battery designs. On-chip MOSFETs provide up to 95% efficiency for critical power supplies, while additional channels operate with external FETs for optimum design flexibility. This optimizes overall efficiency and cost, while also reducing board space.
