EL711DI

1A Fast Transient DC-DC Buck Converter

With Integrated Silicon Magnetics

Description

Features

The EL711DI is the first of a brand new Linear Direct

Replacement (LDR™) buck regulator family designed

for the economical replacement of Low Drop-Out

(LDO) linear voltage regulators. The EL711DI is a

1000mA Power System-on-Chip, (PowerSoC) switch-

mode DC-DC regulator with integrates MOSFETs,

controller, compensation circuit and a proprietary on-

chip silicon inductor. Utilizing a 3x4.5x0.9mm DFN

package, the EL711DI offers high efficiency at an

excellent solution size and is a cost-effective

alternative to LDOs. With an 18MHz switching

frequency, the EL711DI is the fastest in-class buck

regulator with the lowest output ripple. Due to its all-

silicon PowerSoC construction, the EL711DI also

offers superior reliability over standard discrete

DCDC solutions.

The EL711DI showcases Enpirion’s proprietary

monolithic magnetics-on-silicon inductor technology

and is designed to meet the demand of high

performance digital ASICs, DSPs, and FPGAs found

in servers, routers, switches, and base stations.

Enpirion’s PowerSoC solution improves system

design and productivity by offering simple board

layout, small solution size, low cost, high efficiency,

ultra-fast transient response and high performance.
