Demonstration circuit 2341A is a high efficiency synchronous buck DC/DC converter with 4.5V to 20V input range. It can supply 20A maximum load current at 1.5V output. The demo board features the LTC7130 regulator. No external MOSFETs are required. It employs an LTC proprietary current sensing, current mode architecture, allowing the use of a very low DC resistance (DCR) power inductor to maximize efficiency in high current applications. Differential output voltage sensing along with a precision internal reference combine to offer accurate output regulation. The LTC7130 is housed in a 6.25mm × 7.5mm × 2.22mm 63-pin BGA package.
