LTC3130/LTC3130-1
25V, 600mA Buck-Boost
DC/DC Converter with
1.6µA Quiescent Current
DESCRIPTION
The
LTC3130/LTC3130-1
are high efficiency, low noise,
600mA buck-boost converters with wide V
IN
and V
OUT
ranges. For high efficiency operation at light loads,
Burst Mode operation can be selected, reducing the quies-
cent current to just 1.6µA. Converter start-up is achieved
from sources as low as 7.5µW.
The LTC3130/LTC3130-1 employ an ultralow noise, 1.2MHz
PWM architecture that minimizes solution footprint by
allowing the use of tiny, low profile inductors and ceramic
capacitors. Built-in loop compensation and soft-start
reduces external parts count and simplifies the design.
Features include an accurate RUN comparator threshold to
allow predictable regulator turn-on and a maximum power
point control (MPPC) capability that ensures maximum
power extraction from non-ideal sources such as photo-
voltaic panels. The LTC3130-1 includes an internal voltage
divider to provide four selectable fixed output voltages.
Additional features include a power good output, an external
V
CC
input and thermal shutdown.
The LTC3130 and LTC3130-1 are available in thermally-
enhanced 20-lead 3mm
×
4mm QFN and 16-lead MSOP
packages.
