The SP6651A is a high efficiency 800mA synchronous buck regulator from Sipex Corporation, ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6651A features a proprietary control loop, 20µA light load quiescent current, and 0.3Ω power switches, providing excellent efficiency across a wide range of output currents. As the input battery supply decreases towards the output voltage the SP6651A seamlessly transitions into 100% duty ratio operation, further extending useful battery life. The SP6651A is protected against overload and short circuit conditions with a precise inductor peak current limit. Other features include programmable under voltage lockout and low battery detection, externally programmed output voltage down to 1.0V, logic level shutdown control, and 140°C over temperature shutdown.
