Description

The LTC7825 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 VINand 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.The LTC7825 operating switching frequency can be linearly programmed from 100kHz to 1.4MHz. The part is available in a 4mm × 5mm LGA (LQFN) package.ApplicationsConsumer ElectronicsIndustrial ApplicationsBattery Applications
