The FAN49100AUC330X is a 2A, 1.8MHz, TinyPower Buck-Boost Regulator manufactured by ON Semiconductor. It is an integrated voltage regulator designed to provide bidirectional high-efficiency conversion from a wide input voltage range of 2.9V to 16V. The device uses a constant frequency current mode control scheme to ensure stability and excellent transient performance. It is capable of delivering up to 200mA of output current with efficiencies as high as 96%. The device has an external 2.2uH inductor, 10uF ceramic capacitor as well as an external programming resistor for setting the current limit. The device also has additional features such as adjustable soft start to minimize input inrush currents, over current protection, and over voltage and under voltage protection. Its small size and low power dissipation makes it ideal for use in applications such as consumer electronics, battery powered, automotive, wearable, and other portable devices.
