LTC3676HUJ-1 - Brand New Linear Technology Special Purpose Voltage Regulators
-
DESCRIPTION
The LTC®3675 is a digitally programmable high efficiency multioutput power supply plus dual string LED driver IC optimized for high power single cell Li- Ion/Polymer applications. The DC/DCs consist of four synchronous buck converters (1A/1A/500mA/500mA), one synchronous boost DC/DC (1A), and one buck-boost DC/DC (1A) all powered from a 2.7V to 5.5V input. The 40V LED driver can regulate up to 25mA of current through two LED strings with up to 10 LEDs each. The LED driver may also be configured as a general purpose high voltage boost converter.
