POWER SUPPLY ICs INDEX	\| HTML \| PDF \|

[Outline]

This IC 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.
Package is realizes space reduction of the mount area by mounting to the small SSON-6L.
