LTC3532  
Micropower Synchronous  
Buck-Boost DC/DC Converter

DESCRIPTIO  
FEATURES  
The LTC®3532 is a high efficiency, 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 single lithium-ion, multicell alkaline or NiMH ap-  
plications where the output voltage is within the battery  
voltage range.

Operation  
Output Disconnect in Shutdown  
Programmable Oscillator: 300kHz to 2MHz  
Pin Compatible with LTC3440  
The device includes two 0.36Ω N-channel MOSFET  
switches and two 0.42Ω P-channel switches. Switching  
frequencies up to 2MHz are programmed with an external  
resistor. Quiescent current is only 35μA in Burst Mode  
operation, maximizing battery life in portable applica-  
tions. Automatic Burst Mode operation allows the user  
to program the load current for Burst Mode operation or  
to control it manually.
