BP1601 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 sensing strategy is used to minimize the power dissipation and improve system efficiency.
BP1601 Key Features
- 4.5V~24V input voltage range Up to seven 1W LED strings is drived when VIN=12V Higher than 90% efficiency Less than 1uA
