Overview
Product Details
Demonstration circuit 1607 is a multioutput power supply with a pushbutton controller and a dual string LED driver featuring the LTC3675. The LTC3675 operates from a 2.7V to 5.5V input voltage range and has four synchronous buck regulators (1A × 2, 0.5A × 2), a buck-boost regulator (1A), a boost regulator (1A power switch), plus an always-on LDO regulator. The buck regulators may be combined together to create a higher power buck regulator with a single inductor.
The LED boost driver can drive two strings of up to 10 LEDs at up to 25mA each, two strings of 5 LEDs at up to 50mA each, or be configured as a fixed high voltage boost regulator.
