Overview
Description
The RTKA210030DR0000BU demonstration board features the RTKA210030DR0000BU. Capable of delivering up to 3A of continuous current, the RAA210030 is a compact, synchronous step-down, non-isolated complete power supply that is optimized for space-constrained applications. The RTKA210030DR0000BU 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.
