LTC3536

1A Low Noise, Buck-Boost

DC/DC Converter

FeaTures

DescripTion

The LTC^®3536 is an extended V range, fixed frequency,

Regulated Output with Input Voltage Above, Below

or Equal to the Output Voltage

synchronous buck-boost DC/DC converter that operates

from input voltages above, below or equal to the regulated

output voltage. The topology incorporated in the LTC3536

provides low noise operation, making it ideal for RF and

precision measurement applications.

1.8V to 5.5V Input and Output Voltage Range

1A Continuous Output Current for

V ≥ 3V, V

= 3.3V

OUT

1ꢀ Output Voltage Accuracy

Low Noise Buck-Boost Architecture

Up to 95% Efficiency

The device can produce up to 1A of continuous output

current, and it includes two N-channel and two P-channel

MOSFET switches. Switching frequencies up to 2MHz can

be programmed with an external resistor and the oscilla-

tor can be synchronized to an external clock. Quiescent

current is only 32µA in Burst Mode operation, maximizing

battery life in portable applications. Burst Mode operation

is user controlled and improves efficiency at light loads.

Programmable Frequency from 300kHz to 2MHz

Synchronizable Oscillator

Burst Mode^®Operation: 32µA I

Internal 1ms Soft-Start

Output Disconnect in Shutdown

Shutdown Current: 1µA

Short-Circuit Protection

Small Thermally Enhanced 12-Pin MSOP

and 10-Pin (3mm × 3mm) DFN Packages

Other features include a 1µA shutdown current, internal

soft-start, overtemperature protection and current limit.

The LTC3536 is available in 12-pin thermally enhanced

MSOP and 10-pin (3mm × 3mm) DFN packages.
