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.
