Description
The RAA23012x and RAA23013x are 1CH step-down DC/DC converter, 4.5V to 16V input voltage rage and 3A
output current. Auto PFM mode makes devices low power operation at light load, so it makes a system lower
power.
The RAA23012x is suitable for battery backup system using lithium primary cell with built-in battery backup
circuit.
