DFN and 16 Lead MSOP Packages The LT®3509 is a dual, current mode, step-down switching
regulator, with internal power switches each capable of
providing 700mA output current. This regulator provides a
compact and robust solution for multi-rail systems in harsh
environments. It incorporates several protection features
including overvoltage lockout and cycle-by-cycle current
limit. Thermal shutdown provides additional protection.
The loop compensation components and the boost diodes …
