LTC3534

7V, 500mA Synchronous

Buck-Boost DC/DC

Converter

DescripTion

The

LTC

3534

is a wide V

range, highly efficient, fixed

frequency, buck-boost DC/DC converter that operates

from input voltages above, below or equal to the output

voltage. The topology incorporated in the IC provides a

continuous transfer function through all operating modes,

making the product ideal for multi-cell Alkaline/NiMH or

single Lithium-Ion/Polymer applications where the output

voltage is within the battery voltage range.

The LTC3534 offers extended V

and V

OUT

ranges of 2.4V

to 7V and 1.8V to 7V, respectively. Quiescent current is

only 25µA in Burst Mode operation, maximizing battery

life in portable applications. Burst Mode operation is user

controlled and can be enabled by driving the PWM pin

low. If the PWM pin is driven high then fixed frequency

switching is enabled.

Other features include fixed 1MHz operating frequency, a

<1µA shutdown, short-circuit protection, programmable

soft-start, current limit and thermal overload protection.

The LTC3534 is available in the thermally enhanced 16-lead

(3mm

5mm) DFN and 16-lead GN packages.
