300mA High Efficiency Low
Quiescent Current Synchronous
Buck Regulator With Z-mode
The 34726 is a high efficiency, low quiescent current (IQ), synchro-
nous buck regulator, implementing Freescale’s innovative Z-mode ar-
chitecture. Freescale’s Z-mode architecture greatly improves the ripple
performance during light load currents, but still maintains a low quies-
cent current of 65uA, at no load in “Sleepy” Z-mode.
The 34726 accepts an input voltage in the range of 2.7 to 5.5V,
making it ideally suited for single cell Li-Ion based applications. Factory
preset output voltages, ranging from 0.8V to 3.3V, reduce the number
of required auxiliary components. The part is able to provide 300mA of
continuous load current across the input and the output voltage ranges.
The 34726 switches at 2.0MHz to allow the use of small, surface
mount inductors and capacitors to save precious board space.
The 34726 is available in the small, space saving, and low cost, 2x2
UDFN-8 packages. The part is guaranteed for operation over the -25°C
to 85°C temperature range.

µA quiescent current during sleepy Z-mode
• 300mA maximum continuous output current
• Internal 2.0ms soft start
• Thermal and over-current protection
•0.1
µA quiescent current in shutdown (disabled)
• Ultra thin 2x2 UDFN package
• Pb-free packaging designated by suffix code FC
