(3mm × 3mm) DFN and MSOP Packages The LTC®3600 is a high efficiency, monolithic synchronous
buck regulator whose output is programmed with just one
external resistor. The accurate internally generated 50µA
current source on the ISET pin allows the use of a single
external resistor to program an output voltage that ranges
from 0V to 0.5V below VIN. The VOUT voltage feeds directly
back to the error amplifier in unity gain fashion and equals …
