The EL7554IRE is a full-feature synchronous 4A step-down regulator manufactured by Elantec Semiconductor Inc. It is capable of up to 96% efficiency and operates from a 3V to 6V input supply. With internal CMOS power FETs, the device can achieve up to 100% duty ratio, allowing for an output voltage range from 0.8V up to nearly VIN.
The adjustable switching frequency can be set up to 1MHz, enabling the use of small external components and reducing the overall converter footprint to less than 0.58 square inch. The EL7554 operates in constant frequency PWM mode, supporting external synchronization. It includes soft-start and full start-up control to manage in-rush current and allows for precise control of multiple converter start-ups.
This regulator offers a ±5% voltage margining capability for validating system card performance during manufacturing testing. It is housed in a 28-lead TSSOP package with an exposed pad and operates within a temperature range of -40°C to 85°C. The device is suitable for surface mount applications.
Key electrical specifications include a maximum output current of 4A, a switching frequency range of 0.2MHz to 1MHz, and an input voltage range of 3V to 6V. The output voltage is adjustable from 0.8V.
