General Description
The EL7556AC is an adjustable synchronous DC:DC switching regulator optimized for a 5V input and 1.0-3.8V output. By combining integrated NMOS power FETS with a fused-lead package the EL7556AC can supply up to 6A continuous output current without the use of external power devices or discrete heat sinks, thereby minimizing design effort and overall system cost.
