The RTKA210040DR0000BU demonstration board features the RAA210040.
Capable of delivering up to 4A of continuous current, the RAA210040 is a compact, synchronous step-down, non-isolated complete power supply that is optimized for space-constrained applications. The RAA210040 is based on a peak current mode PWM control scheme that provides a fast transient response and excellent loop stability. The switching frequency is programmable from 500kHz to 4MHz with either the external resistor or synchronization to an external clock through the SYNC pin.
The RTKA210040DR0000BU demonstration board is a 1×1 inch 4-layer FR4 board with 2oz. copper on all layers. It is optimized to minimize the complete power module solution size. Operating from a single 2.7V to 5.5V input power rail, the RTKA210040DR0000BU demonstration board offers adjustable output voltages down to 0.6V, up to 95% efficiency, and better than 1.5% accuracy over line, load, and temperature. A dedicated enable pin and power-good flag allows for easy system power rails sequencing.
