RAA230222 - Renesas

RAA230222 Dual Step-Down DC/DC Converter

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. R18DS0017EJ0000 REV.0.00 Aug.
