DC2736A

DC2736A demonstration circuit is a single output high voltage nonisolated synchronous step-down converter that drives all GaN transistor power stage. It features the LTC®7800, a low quiescent current high frequency (programmable fixed frequency from 320KHz up to 2.25MHz) synchronous step-down DC/DC controller housed in a small 3mm × 4mm QFN package. This DC2736A operates over an input voltage range from 30V to 55V, while the LTC7800 can operate up to 60V. This demo board produces a 12V output voltage with up to 20A output current, and is configured with a sense resistor for current sensing. A mode selector allows the DC2736A to operate in forced continuous operation, pulse-skipping or Burst Mode® operation during light loads.
