Some of the key benefits for the LTC7851 are that it supports one to four outputs, and each output has its own differential amplifier for remote output voltage sensing to compensate for voltage drops in trace runs and interconnects. The LTC7851 operates with voltage mode control and has an internal current share loop. This current share loop equalizes current between phases when paralleled, enabling less than ±3% current balance between phases both in a steady state condition and during a transient event. The Linear Technology LTC7851 is designed for step-down conversion from an input voltage from 3V to 27V and produces output voltages ranging from 0.6V to 5V. In addition, the LTC7851 operates with a VCC supply voltage from 3V to 5.5V to power the IC. This Vcc voltage is also used to power DrMOS and power blocks, so is not just required to power the LTC7851/-1.
