Description

DESCRIPTIONThe EVNB675-L-00A is an evaluation board forthe NB675GL, the lower quiescent currentversion of NB675.The Evaluation Board can deliver 10Acontinuous load current from a 5V to 22V inputwith excellent load and line regulation.Constant-On-Time (COT) control modeprovides fast transient response and eases loopstabilization.The Evaluation Board can be turned on or shutdown via a remote ON/OFF input that isreference to ground. This input is compatiblewith popular logic devices.This part requires minimum number of externalcomponents and is available in QFN21(3mmx4mm) package
