Fully Integrated 17V/8A Switched Capacitor 2:1 Converter Configurable as a Voltage Divider, Doubler, or Inverter

The LT®7826 is a fully integrated monolithic DC-to-DC converter. It 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. It features integrated bootstrap diodes and provides a compact and cost-effective solution for battery applications requiring current limit protection. The 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.
