EL7554
EL7554 is Monolithic 4A DC/DC Step-Down Regulator manufactured by Renesas.
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 ponents, making the whole converter occupy less than 0.58 square inch with ponents on one side of the PCB. The EL7554 operates at constant frequency PWM mode, making external synchronization possible. The EL7554 Features soft-start and full start-up control, which...
