Renesas Electronics Simple Power Supply ICs

Renesas Electronics introduces 16 V input capable synchronous buck regulators that deliver up to 3 A continuous current to loads at voltages as low as 0. 8 V. The power supply ICs are suitable for systems requiring low power consumption in standby mode and backup power in case of power outage.

The devices target applications in the industrial, office equipment, consumer, networking, smart grid and other fields. By reducing the power supply design workload, the devices lower power consumption and improve the compactness of the overall system for improved power efficiency and lower BOM cost.

The Simple Power Supply ICs are available in four series with different DC/DC converter output counts and output voltages. Battery backup functionality is availability in the RAA23012X series, RAA23013X series, RAA23022X series and RAA23023X series. Each series comprises three product versions.

The auto PFM mode reduces power consumption per DC/DC converter to 100 μA, enabling lower power consumption than conventional DC/DC converter configurations. An integrated battery backup function provides lower system cost and reduced component count (RAA23012X series and RAA23022X series only).

The RAA23022x series and RAA23023x series incorporate two DC/DC converters in a single package, allowing for a reduction of approximately half the number of power supply IC peripheral components. To support all aspects of system development, including power supplies, Renesas offers a full complement of system solutions.
