RAA23022x RAA23023x
Datasheet
RAA23022x RAA23023x
16V Input, 3A, Dual Step-Down DC/DC Converter
+ Battery Backup
Description
The RAA23022x and RAA23023x are dual 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 RAA23022x is suitable for battery backup system using lithium primary cell with built-in battery backup
circuit.
