描述
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.
