The LTC®3127 is a wide VIN 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 × 3mm × 0.75mm) DFN packages and 12-lead MSOP packages.
