MAX1947 Overview
Features ♦ Low Input (0.7V) and Output (1.8V) Voltage Capability ♦ Internal Synchronous Rectifier ♦ High 94% Efficiency ♦ Fixed Output Voltages: It features an internal 800mA switch and synchronous rectifier to achieve up to 94% efficiency and to eliminate the need for an external Schottky diode. High-frequency switching (up to 2MHz) results in low ripple and small external ponents, while automatic pulse skipping at...
