NCP5030 High Power Lighting Evaluation Board Schematic Operation CAUTION: L101 selection depends on the output current, 1. Exceeding the maximum input voltage may VLF5014A4R7M1R1 is recommended at output current damage NCP5030 permanently under 500 mA, and RLF7030T4R7M3R4 is recommended 2. Too long time duration at over output current when output current is larger than 700 mA. may decrease LED life time or even damage The power supply of NCP5030 should be from 2.7 V to LED 5.5V. Maximum input voltage is 7.0V and maximum continuous output current is 900 mA. Table 1.
