DC1340A - LTC3569EUD Demo Board | Triple Buck Regulator with 1.2A and Two 600mA Outputs and Individual Programmable References

Demonstration circuit 1340 is a triple output regulator consisting of three constant-frequency step-down converters integrated into LTC3569. DC1340 has an input voltage range of 2.5V to 5.5V, with regulators capable of delivering 1.2A or 600mA of load current on corresponding output. The three regulators operate independently with individual Enable pins and enter pulse skipping or burst mode at low loads for increasing efficiency. The DC1340 is a very efficient circuit with efficiency reading above 90%. High operating frequency of 2.25MHz allows exclusive use of the small size, low profile surface mount components. These features plus internal compensation circuits and extremely low quiescent current make the DC1340 demo board an ideal circuit for use in battery-powered, hand-held applications.
