LTC3127
1A Buck-Boost DC/DC
Converter with Programmable
Input Current Limit
DESCRIPTION
The
LTC
®
3127
is a wide V
IN
range, highly efficient, 1.35MHz
fixed frequency buck-boost DC/DC converter that operates
from input voltages above, below or equal to the output
voltage. The LTC3127 features programmable average
input current limit, making it ideal for power-limited input
sources. The input current limit is programmed with a
single resistor and is accurate from 0.2A to 1A of average
input current.
The topology incorporated provides a continuous
transfer function through all operating modes. Other
features include <1μA shutdown current, pin-selectable
Burst Mode operation and thermal overload protection.
The LTC3127 is housed in thermally enhanced 10-lead
(3mm
