LTC3533
2A Wide Input Voltage
Synchronous Buck-Boost
DC/DC Converter
Description
The
LTC
®
3533
is a wide V
IN
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 single cell lithium-ion/polymer
or multi-cell alkaline/NiMH applications where the output
voltage is within the input voltage range.
The LTC3533 features programmable Burst Mode oper-
ation, extended V
IN
and V
OUT
ranges down to 1.8V, and
increased output current. Switching frequencies up to
2MHz are programmed with an external resistor. The Burst
Mode threshold is programmed with a single resistor from
the BURST pin to GND.
Other features include 1µA shutdown current, short circuit
protection, programmable soft-start, current limit and
thermal shutdown. The LTC3533 is housed in the thermally
enhanced 14-lead (3mm
