Demonstration Board , RAA210040, Synchronous Step Down Regulator, Power Management-Voltage Regulator

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. 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. Applications include telecom, industrial, optical, medical equipment, point-of-load conversions, MCU, MPU, DSP and FPGA.
