Synchronous Stepdown Regulator with Programmable Reference
The standard design of a general purpose switching step-down regulator relies on a control loop that requires the user to attenuate the output signal to compare to a voltage reference. By thinking outside the box and designing a regulator that relies on a unity-gain control loop and a current reference, the LTC3600 can create unique and elegant application circuits that cannot be easily duplicated by other monolithic switching regulators. The ability to operate in a unity-gain configuration allows board trace to be used as ballasting to ensure even load sharing. The LTC3600 can also generate a tracking supply alongside a LT3080 linear regulator to build a high-efficiency, low noise supply rail.
