EL7566DRE

Product Summary

The EL7566DRE is a full-feature synchronous step-down regulator capable of up to 6A and 96% efficiency. The device operates from 3V to 6V input supply (VIN). With internal CMOS power FETs, the EL7566DRE can operate at up to 100% duty ratio, allowing for an output voltage range of 0.8V to nearly VIN. An adjustable switching frequency up to 1MHz enables the use of small components, thereby reducing board area consumption to under 0.72sq-in on one side of a PCB. The EL7566DRE also offers a voltage margining capability that shifts the output voltage ±5% for validation of system card performance and reliability during manufacturing tests. A junction temperature indicator conveniently monitors the silicon die temperature, saving time in thermal characterization. The EL7566DRE is suitable for Point-of-regulation power supplies, FPGA Core and I/O supplies, DSP, CPU Core, and IO supplies, Logic/Bus supplies and Portable equipment.
