SP6655 -High Efficiency 400mA Synchronous Buck Regulator

The SP6655 is a 400mA synchronous buck Regulator which is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6655s proprietary control loop 20 light load quiescent current, and 0.3, Power Switches provide excellent efficiency across a wide range of output currents. As the input battery supply decreases towards the output voltage, the SP6655 seamlessly transitions into 100% duty ratio operation, further extending useful battery life. The SP6655 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 over temperature shutdown.
