Analog Devices LT3072

The LT3072 is ideal for high performance FPGAs, microprocessors and sensitive RF communication supply applications. The LT3072 incorporates a unique tracking feature (VIOC) to control the upstream buck regulator(s) powering the inputs. VIOC adaptively servos the buck regulator to maintain the LT3072 input-to-output voltage differential to 300mV at maximum load and 450mV at light load, minimizing power dissipation with less input capacitance.
