NCP5030MTTXGEVB:High Power Lighting Evaluation Board
The NCP5030 is a fixed frequency PWM buck-boost converter optimized for constant current applications such as driving high-powered white LED. The buck-boost is implemented in an H-bridge topology and has an adaptive architecture where it operates in one of three modes: boost, buck-boost, or buck depending on the input and load condition. This device has been designed with high-efficiency for use in portable applications and is capable of driving up to 1.2A pulse current and 900mA continuous current into a high power LED for camera flash, flashlight, torch and similar applications. This demo board demonstrates the overall NCP5030 capabilities and offers very easy current programming. The output current is fully configurable via the usage of 4 external resistors and corresponding jumper headers.
