DESCRIPTION

The LTC®7825 is a fully integrated monolithic DC/DC converter.

It achieves very high efficiency with a switched

capacitor architecture in applications with 2:1 input to

output voltage ratio. The LTC7825 input can survive voltage

transient up to 40V when protected by an optional

MOSFET between VIN and VHIGH. The input and output

are fully disconnected during short-circuit conditions.

The LTC7825 features integrated bootstrap diodes and

provides a compact and cost-effective solution for high

power intermediate bus applications requiring current

limit protections.
