Analog Devices Inc. DC2727A Demo Board for LTC3892 DC/DC Controllers

Analog Devices Inc. DC2727A Demo Board for LTC3892 DC/DC Controllers is a high-input voltage, high-efficiency dual-output DC/DC converter. The DC2727A features the LTC®3892‑2, a low IQ, dual output, 2-phase synchronous step-down DC/DC controller. This Analog Devices board operates over a 6V to 40V input voltage range and produces 3.3V at 10A and 12V at 3A output. 


  • 12V output is designed using a SEPIC converter for a stable output voltage from an input voltage that can be above, below or equal to the output voltage
  • 3.3V is provided using a synchronous step-down converter
  • Output voltages can easily be changed with certain modifications
  • Gate drive voltage can be adjusted from 5V to 10V allowing the use of logic or standard level MOSFETs
  • DC2727A supports three operation modes: forced continuous mode, pulse-skipping and Burst Mode® operation during light loads
  • Forced continuous mode reduces output voltage ripple and yields a low noise switching spectrum
  • Pulse-skipping and burst modes increased efficiency at light loads
  • Both outputs of the DC2727A switch out of phase to reduce input filtering
  • DC2727A supports selectable current limit and provides very low dropout operation with its 99% duty cycle capability
  • Standard operating frequency of 250kHz, but can be adjusted in a range between 75kHz and as high as 850kHz
  • Integrates the bootstrap diodes which simplifies the design
  • Designed to support multiple footprints of input/output capacitors and inductors to accommodate variety of applications
