DESIGN IDEASвЂ‰L ВµModule Regulator Fits a (Nearly)
Complete Buck-Boost Solution
in 15mm Г— 15mm Г— 2.8mm for
4.5VвЂ“36V VIN to 0.8VвЂ“34V VOUT
Linear Technology offers a number of
high efficiency synchronous 4-switch
buck-boost DC/DC converter solutions for applications where VOUT falls
within the range of VIN. The LTM4605,
LTM4607 and LTM4609 ВµModule
regulators are nearly self-contained
buck-boost solutions that share pincompatible 15mm Г— 15mm Г— 2.8mm
packages. The package includes the
controller, four power FETs and a
number of other discrete components.
Only an external inductor, a sensing
resistor, a voltage setting resistor and
a few input and output capacitors are
needed to complete a high efficiency
buck-boost converter.
Table 1 shows the input voltage,
output voltage and current specifications of these three buck-boost
ВµModule regulators. The LTM4609
is the latest addition to this family. …
