The LTC7130 is Linear Technology's highest current “pseudo-monolithic” synchronous buck regulator. It resembles a µModule with a BGA package except that it has an external inductor. It is a current mode synchronous step-down monolithic converter that can deliver up to 20A continuous load current. The device employs a unique architecture which enhances the signal-to-noise ratio of the current sense signal, allowing the use of a 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. Its BGA package is compact and thermally efficient.
