EL7556DCMZ-T13集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

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.
