LTC7825AV#PBF

LTC7825AV#PBF is a fully integrated, switched capacitor DC/DC converter with overvoltage and overcurrent protections. It achieves very high efficiency with a switched capacitor architecture in applications with a 2:1 input-to-output voltage ratio. The LTC7825 input can survive voltage transients 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. Application includes consumer electronics, industrial applications, and battery applications.
