The EA3327 is a dual channel power management IC .

It integrates two 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 and the independent enable control makes the designer have the greatest flexibility to optimize timing for power sequencing purposes.

All converters feature complete protection functions, including cycle-by-cycle current limit, short circuit protection, OTP and UVLO protection.

The EA3327 is available in a tiny 12 pin DFN 3x3 package and can save the PCB area.
