Description

Demonstration circuit 1928A is a single output synchronous buck converter featuring the LTC®3867EUF in a 24-lead 4mm x 4mm QFN package.The DC1928A is configured with a sense resistor. Inductor DCR sensing circuit is optional. Using the inductor’s DCR as the sense element instead of the onboard sense resistor saves cost, board space while improving efficiency. Using a sense resistor provides more accurate current limit.The board has a lot of features including an internal 5V linear regulator for bias, output voltage remote-sense, programmable nonlinear control to improve load transient performance, programmable thermal shutdown, an optional temperature compensated DCR sense circuit, and selectable continuous, pulse-skipping or Burst Mode® operation. Synchronization to an external clock is also possible.The input voltage range is from 18V to 36V. The LTC3867 data sheet gives a complete description of the part, operation and application information and must be read in conjunction with this demo manual for DC1928A.
