BP1601 General Description

BP1601 is a step-up DC/DC converter designed to drive high brightness LED from 4.5V to 24VDC input voltage . Typically in 12VDC input voltage, up to seven 1W LED strings is able to be drived. BP1601 works in current mode to control LED current, it set the LED current by sense resistor, this low-side.
