The RAA210610 power module is a single-channel, synchronous step-down, non-isolated complete power supply, capable of delivering up to 15A of continuous current. Operating from a single 7V to 54V wide input power rail and integrating the controller, power inductor, and MOSFETs, the RAA210610 requires only a few external components to operate and is optimized for space constrained applications. The RAA210610 offers an adjustable output voltage range of 0. 6V to 42V with better than 1. 5% accuracy over line, load, and temperature. It achieves up to 97. 6% efficiency and provides fast transient response and excellent loop stability. The operating frequency can also be synchronized with an external clock signal. The RAA210610 implements a selectable Pulse Skipping Mode (PSM) with Diode Emulation Mode (DEM) to improve light-load efficiency for battery related applications. A programmable soft-start reduces the inrush current from the input supply while a dedicated enable pin and power-good flag allow for easy system power rails sequencing with voltage tracking capability. Input Undervoltage Lockout (UVLO), over-temperature, programmable overcurrent, output overvoltage, and output pre-bias start-up protections ensure safe operations under abnormal operating conditions. The RAA210610 is available in a compact RoHS compliant thermally-enhanced 19mmx13mmx5. 3mm HDA package.
