DC1041A-A

LINEAR TECHNOLOGY DC1041A-A Demonstration Board for 5Vin to 20Vin, 12A Step-Down µModule Regulator

The is a demonstration board featuring LTM4601EV DC to DC µModule regulator. The LTM4601EV is a complete 12A step down switch mode DC to DC power supply with onboard switching controller, MOSFETs, inductor and all support components. The low profile and light weight package easily mounts in unused space on the back side of PC boards for high density point of load regulation. The input voltage range is from 4.5V to 20V. The output voltage is jumper selectable for popular voltages from 0.6V to 5V. The PLLIN pin supports synchronizing the µModule regulator to an external clock. The TRACK/SS pin allows the user to program output ramp up and ramp down rates which may coincidentally or ratiometrically track with another supply"s output if desired. Output voltage margining of ±5% from the nominal value is available via the margin control pins MARG0 and MARG1.
