Description

The RAA23014x and RAA23015x are 1CH step-down DC/DC converter, 7V to 28V input voltage range. Auto

PFM mode makes devices low power operation at light load, so it makes a system lower power.

The RAA23014x is suitable for battery backup system using lithium primary cell with built-in battery backup

circuit.
