MM3472

0.6A step-down DC-DC convertor IC MM3472 0.6A step-down DC-DC convertor IC Monolithic IC MM3472 Outline 　MM3472 series is a synchronous rectifying step-down DC/DC converter which is foucused on space minimizing design, high oscillation frequency (2.25MHz) and high efficiency by fewer external components (1 coil and 2 capacitors) in order to meet miniaturization and low power consumption. The package realizes space reduction of the mount area by mounting to the small SOT-26A and SSON-6L.
