® FO R DED 566 N E L7 OM M S Data EE ESheet RE C T O N D N EW ESI G NS EL7556D August 1, 2005 FN7339.1 Integrated Adjustable 6 Amp Synchronous Switcher The EL7556D is an adjustable synchronous DC:DC switching regulator optimized for a 5V input and 1.0V-3.8V output. By combining integrated NMOS power FETS with a fused-lead package, the EL7556D 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. On-chip resistorless current sensing is used to achieve stable, highly efficient, current-mode control. The EL7556D also incorporates the VCC2DET function to directly interface with the Intel P54 and P55 microprocessors.
