SNVS497F – NOVEMBER 2008 – REVISED SEPTEMBER 2016 LM2734x and LM2734x-Q1 2-MHz, 1.5-A or 2-A, Wide Input Range, Step-Down, DC-DC
Regulator With Frequency Synchronization
1 Features 3 Description The LM2734x and LM2734x-Q1 regulators are
monolithic, high-frequency, PWM step-down DC-DC
converters in 10-pin WSON and 10-pin MSOPPowerPAD packages. They contain all the active
functions to provide local DC-DC conversion with fast
transient response and accurate regulation in the
smallest possible PCB area. 1 2 Space-Saving, 3 mm Г— 3 mm 10-Pin WSON and
MSOP-PowerPAD Packages
