dc1725a DC1725A LT3759EMSE Boost Demo Board | VIN = 1.8V to 4.5V, VOUT = 5V @ 2A Demonstration circuit 1725A features LT3759 in a 485kHz boost converter, designed for a 5V/2A output from a 1.8V to 4.5V input. The LT3759 is a current mode DC/DC Boost/SEPIC/Inverting controller operating over an input range of 1.6V to 42V. Thanks to a novel FBX pin architecture, the LT3759 allows both positive and negative output feedback voltages. DC1725A
