FEATURES
LTC3532
Micropower Synchronous
Buck-Boost DC/DC Converter
DESCRIPTIO
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.
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.
Other features include a 1μA shutdown, soft-start control,
thermal shutdown, and peak current limit. The LTC3532 is
available in a low profile (0.75mm) 10-lead (3mm × 3mm)
DFN and 10-lead MSOP packages.
