Analog Devices Inc. LT7826 Integrated Monolithic DC-DC Converter

Analog Devices LT7826 Fully Integrated Monolithic DC-DC Converter achieves very high efficiency with a switched capacitor architecture in applications with an input-to-output voltage ratio of 2:1 (divider), 1:2 (doubler), or 1:1 (inverter). The LT7826 can handle a maximum voltage of 17V and provide a maximum output current of 8A, with fault protection. The converter features integrated bootstrap diodes and provides a compact, cost-effective solution for battery applications requiring current limit protection. The Analog Devices LT7826 operates at a fixed 500kHz switching frequency, while synchronization is available through the MODE pin for frequency tuning and interleave operation. The part is available in a 3mm x 3mm LFCSP package.
