Beschreibung

This document explains the function and use of the RTQ2822A evaluation board (EVB), the RTQ2822A is a high-performance, synchronous step-down converter that can deliver up to 12A output currentvwith an input supply voltage range of 4.5V to 17V. The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode for bootstrap circuit to offer a very compact solution. This document explains the function and use of the RTQ2822A evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to meet individual requirements.
