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 wi...
