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 dep ? Efficiency: 87% at 500 mA and 3.3 V VIN\n? Internal Synchronous Rectifier, No Schottky Diodes\n? Adjustable Switching Limit Current to Optimize inductor size\n? 0.3 μA Shut-down Control with True-Cut off\n? Input Voltage Range from 2.7 V to 5.5V\n? 200 mV Feedback Voltage\n? Output Over-voltag;
