The evaluation circuit EVAL-LTC7893-AZ is a single output synchronous step-up converter that drives GaN field effect transistors (FETs). The EVAL-LTC7893-AZ evaluation board features 100V GaN FETs.The EVAL-LTC7893-AZ features the LTC®7893: a low quiescent current, high frequency (programmable fixed frequency from 100kHz up to 3MHz), step-up DC/DC synchronous controller, with a dedicated driver feature for GaN FETs, which can also be used to drive logic-level silicon FETs.The EVAL-LTC7893-AZ operates over an input voltage range from 8V to 36V and produces a 48V output with load current up to 18A (without heatsink). A mode selector allows the EVAL-LTC7893-AZ to operate in forced continuous operation, pulse-skipping or Burst Mode® operation during light loads. The EVAL-LTC7893-AZ is set to 500kHz switching frequency, which results in a small and efficient circuit.
