LTC3129
15V, 200mA Synchronous
Buck-Boost DC/DC Converter
with 1.3µA Quiescent Current
DescripTion
The
LTC
®
3129
is a high efficiency, 200mA buck-boost
DC/DC converter with a wide V
IN
and V
OUT
range. It includes
an accurate RUN pin threshold to allow predictable regula-
tor turn-on and a maximum power point control (MPPC)
capability that ensures maximum power extraction from
non-ideal power sources such as photovoltaic panels.
The LTC3129 employs an ultralow noise, 1.2MHz PWM
switching architecture that minimizes solution footprint by
allowing the use of tiny, low profile inductors and ceramic
capacitors. Built-in loop compensation and soft-start
simplify the design. For high efficiency operation at light
loads, automatic Burst Mode operation can be selected,
reducing the quiescent current to just 1.3µA.
Additional features include a power good output, less than
10nA of shutdown current and thermal shutdown.
The LTC3129 is available in thermally enhanced 3mm ×
3mm QFN and 16-lead MSOP packages. For fixed output
voltage options, see the functionally equivalent LTC3129-1,
which eliminates the need for an external feedback divider.
