EL7554 - Monolithic 4A DC/DC Step-Down Regulator

Features

  • soft-start and full start-up control, which eliminates the in-rush current and enables users to control the start-up of multiple converters to any configuration with ease. The EL7554 also offers a ±5% voltage margining capability that allows raising and lowering of the supplies derived from the EL7554 to validate the performance and reliability of syst.

EL7554 Monolithic 4A DC/DC Step-Down Regulator The EL7554 is a full-feature synchronous 4A step-down regulator capable of up to 96% efficiency. This device operates from 3V to 6V VIN input supply. With internal CMOS power FETs, the device can operate at up to 100% duty ratio, allowing for output voltage range from 0.8V up to nearly VIN.The adjustable high switching frequency of up to 1MHz enables the use of small components, making the whole converter occupy less than 0.58 square inch with components on one side of the PCB. The EL7554 operates at constant frequency PWM mode, making external synchronization possible.
