Analog Devices LTC7130

Beschreibung

monolithic converter that can deliver up to 20A continuousload current. It employs a unique architecture which enhancesthe signal-to-noise ratio of the current sense signal, allowingthe use of a very low DC resistance power inductor tomaximize efficiency in high current applications. This featurealso reduces the switching jitter commonly found in lowDCR applications. The LTC7130 also includes a high speeddifferential remote sense amplifier and a programmable currentsense limit that can be selected from 10mV to 30mV toset the output current limit up to 20A. In addition, the DCRtemperature compensation feature limits the maximumoutput current precisely over temperature.The LTC7130 also features a precise 0.6V reference with aguaranteed limit of ±0.5% that provides an accurate outputvoltage. A 5V to 20V input voltage range supports a widevariety of bus voltages and various types of batteries.The LTC7130 is offered in a compact and low profile BGA packageavailable with SnPb/RoHS compliant terminal finishes.
