The RRM12120 is a fully PMBus-enabled DC/DC step-down power supply capable of delivering up to 20A of current from a compact 10mm × 13mm × 5.9mm thermally enhanced BGA package.
Operating across an input voltage range of 4.75V to 15V, the RRM12120 offers adjustable output voltages down to 0.45V and achieves up to 94% efficiency. The RRM12120 implements the proprietary Renesas digital synthetic current modulation scheme to achieve an industry-leading combination of transient response, ease of tuning, and efficiency across the full load range. With minimal external components, simple configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance regulator has never been easier.
A standard PMBus interface with PMBus v1.3 compatibility facilitates device configuration, addresses sequencing and fault management, provides real-time full telemetry and point-of-load monitoring, and detailed fault reporting. All of these features are conveniently accessible through the PowerNavigator™ software tool.
A fully customizable cycle-by-cycle current (peak overcurrent and peak undercurrent limit), voltage, and temperature protection scheme is capable of latching off or restarting the output in response to system faults.
Renesas' PowerNavigator™ software allows simple configuration and monitoring of multiple Digital-DC devices using a PC with a USB interface.
