SY22173 is a high efficiency step down regulator capable of driving 1.0A white LED from up to 30V input. It integrates the low RON MOSFET and internal compensation. The 1MHz switching frequency allows the use of very small inductor. This, along with the small SOT23-6 package, achieves an extremely small LED driver design.
