Introduction
Electronic devices are becoming smaller while the power
requirements are increasing to satisfy ever more functionality. To preserve power and manage heat, switching
regulators are desirable because of their high efп¬Ѓciency
compared to linear regulators.
The LT3506 and the LT3506A are examples of how to
squeeze power out of a supply without overheating the
end product. These are dual 1.6A step-down monolithic
regulators that simplify the lives of system engineers. They
eliminate the need for external power switches, thereby
reducing solution size and BOM cost. Their outputs can
be as low as 0.8V, satisfying the needs of the latest DSPs.
Integrated dual output channels reduce the part count,
while anti-phase switching of the two channels maximizes
efп¬Ѓciency and reduces input current ripple and EMI. Both
