The EA8121 is a dual channel high switching frequency, high efficiency synchronous buck regulator, designed to operate from 2.5V to 5.5V input voltage range.

Built-in low RDS(ON) high/low side Power-MOSFETS not only reduce external components and has up to 95% efficiency, ideal for 1A output current applications.

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.

The EA8121 features 100% duty cycle low dropout operation, extending battery life in portable systems.

The EA8121 is available in the DFN 3x3-10 package and easy to use.
