Analogue Devices has managed to create a 500W switched-capacitor power chip for fixed ratio power conversion at up to 72V and 99% efficiency. Power density up to 4,000W/in3 is claimed. The main application foreseen for the chip, the LTC7820, is 48V non-isolated dc bus conversion, although it is capable of up, down and inverting conversion at ...
