LP3219
1.5MHz, 2A Step-Down Converter
概述
The LP6304B is a 2A buck converter of 4-CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter. It integrates four synchronous buck converters and can provide high efficiency output at light load and heavy load operation. The internal compensation architecture simplifies the application circuit design. Besides, the independent enable control makes the designer have the greatest flexibility to optimize timing for power sequencing purposes. The LP6304B is available in a 24 pin TQFN 4x4 package.
