Additional Details

The LTC7130 is a current mode synchronous step-down monolithic converter that can deliver up to 20A continuous load current. It employs a unique architecture which enhances the signal-to-noise ratio of the current sense signal, allowing the use of a very low DC resistance power inductor to maximize efficiency in high current applications. This feature also reduces the switching jitter commonly found in low DCR applications. The LTC7130 also includes a high speed differential remote sense amplifier and a programmable current sense limit that can be selected from 10mV to 30mV to set the output current limit up to 20A. In addition, the DCR temperature compensation feature limits the maximum output current precisely over temperature.

The LTC7130 also features a precise 0.6V reference with a guaranteed limit of ±0.5% that provides an accurate output voltage. A 5V to 20V input voltage range supports a wide variety of bus voltages and various types of batteries.

The LTC7130 is offered in a compact and low profile BGA package available with SnPb/RoHS compliant terminal finishes.
