MAX1567 Description
They improve performance, ponent count, and size pared 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.
