The EL7554 is a full-feature synchronous 4A step-down regulator capable of up to 96% efficiency
The EL7554 is a full‑feature synchronous 4 A step‑down regulator that operates from a 3 V to 6 V input and can deliver output voltages as low as 0.8 V. It offers up to 96 % efficiency, an adjustable switching frequency up to 1 MHz, soft‑start, voltage margining, and a junction‑temperature indicator, making it suitable for point‑of‑regulation supplies, FPGA, DSP, CPU cores, and portable equipment.
The datasheet details absolute maximum ratings, DC electrical specifications, pin functions, typical performance curves, and thermal‑management guidelines. It also includes ordering information, package dimensions (28‑lead HTSSOP), and layout recommendations for optimal heat dissipation.
