SP6654ER

The SP6654ER is a 800mA synchronous buck regulator which is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6654's proprietary control loop, 20µA light load quiescent current, and 0.3 power switches provide excellent efficiency across a wide range of output currents.

The feature of SP6654ER are as follows: (1)Ultra-low 20A Quiescent Current; (2)98% Efficiency Possible; (3)800mA Output Current; (4)2.7V to 5.5V Input Voltage Range; (5)Output Adjustable Down to 1.0V; (6)No External FET.s Required; (7)1.25A Inductor Peak Current Limit; (8)100% Duty Ratio Low Dropout Operation; (9)80A Light Load Quiescent Current in Dropout; (10)Logic Shutdown Control; (11)Programmable UVLO; (12)Small 10pin MSOP Package; (13)Power Good Indicator; (14)industry Standard 10 Pin MSOP and and Small DFN Package.

The absolute maximum ratings of the SP6654ER are: (1)PVIN,VIN: 6V; (2)All other pins: -0.3V to VIN+0.3V; (3)PVIN, PGND, LX current: 2A; (4)Storage Temperature: -65 °C to 150 °C; (5)Operating Temperature: -40°C to +85°C; (6)Lead Temperature: 300 °C.
