DESIGN IDEASвЂ‰L 0.25in2 Г— 1.8mm Dual Output
Converter for Li-Ion to 3.3V and 1.8V
by John Canfield Introduction
One quarter inch square. That is all
the area needed for a complete Li-Ion
to dual output, buck and buck-boost
converter. FigureВ 1 shows a compact
dual output converter made possible
by the LTC3522вЂ”a complete, high
efficiency, dual rail power supply solution in a 3mm Г— 3mm QFN. As shown,
only a few external components are
required, and they can all be low profile
(в‰¤1mm)вЂ”perfect for the demanding
space requirements of even the most
compact portable electronic devices.
The LTC3522 combines a monolithic
buck-boost converter and synchronous buck converter in a single, low
profile 0.75m Г— 3mm Г— 3mm 16-lead
QFN. Soft-start and feedback loop
compensation circuitry is included in
the IC. An entire application circuit
for a dual converter requires only
the IC, inductors, bypass capacitors …
