IC revision1.0

Description

The RTKA211412DE0000BU board demonstrates and quickly evaluates the RAA211412, a DC/DC step-down regulator with 630kHz switching frequency.The RAA211412 is a DC/DC step-down (Buck) regulator that supports a wide operating input voltage range (from 5.8V to 45V) and adjustable output voltage. It can deliver up to continuous 1A output current with premium load regulation and lineregulation performance.The evaluation board implements a complete buck regulator using the RAA211412. The output voltage isset to 3.3V by default but can be adjusted bychanging the resistor values in the feedback network.
