MAX1920 converters equivalent, 400ma step-down dc-dc converters.
Internal synchronous rectification greatly improves efficiency and eliminates the external Schottky diode required in c.
The MAX1920/MAX1921 step-down converters deliver over 400mA to outputs as low as 1.25V. These converters use a unique proprietary current-limited control scheme that achieves over 90% efficiency. These devices maintain extremely low quiescent supply .
