Preliminary Datasheet

LP6303

Buck 2A, 3-Channel Power Management IC

General Description

The LP6303 is a 2A buck converter of 3-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 LP6303 is available in a 24 pin TQFN 4x4

package.
