The ASLx500SHN and ASLx41xSHN Evaluation Board (EVB) features the ASL4500SHN, a highly integrated and flexible four-phase DC-to-DC boost converter IC and two ASL3416SHN, a three-channel buck mode LED driver IC delivering constant average DC current. The kit is designed to drive six LED strings with 150 mA to 1.6 A and 2 V to 60 V LED string voltage. In a default application a microprocessor unit (MCU) controls the devices through a serial peripheral interface (SPI).
