DescripTion  
The LTC®3536 is an extended V range, fixed frequency,  
n
Regulated Output with Input Voltage Above, Below  
IN  
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.

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

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.
