DC1040A-A - LTC3544EUD Demo Board | Quad Sync Buck, 2.25V ≤ VIN ≤ 5.5V, Iout = 100mA, 200mA(x2) & 300mA

Demonstration circuit 1040 is a quad output regulator consisting of four constant-frequency step-down converters integrated into the LTC3544. DC1040 has an input voltage range of 2.25V to 5.5V, with regulators capable of delivering 100mA, 200mA, 200mA and 300mA of output current. The four regulators operate independently with individual RUN pins and enter pulse skipping mode at low loads to reduce output ripple. The "-A" version is for the LTC3544EUD (Burst Mode) and the "-B" version is for the LTC3544BEUD (Pulse Skipping Mode).
