Tiny 4A switching regulator simplifies designs, improves reliability

Maxim Integrated Products' MAX15040 is a low-voltage (2.4V to 3.6V), synchronous switching regulator in a 2mm x 2mm wafer-level package (WLP). This miniature step-down regulator integrates MOSFETs to simplify design, minimize EMI, improve reliability, and save board space.

The MAX15040 operates from a fixed 1MHz switching frequency to further reduce total solution size, as it allows all-ceramic-capacitor designs. Offering efficiencies up to 94% at full load current (4A), this point-of-load regulator minimizes power loss in applications such as telecom, networking, and server equipment.

Key highlights:

• Internal 15mΩ RDS(ON) MOSFETs
• Continuous 4A Output Current
• ±1% Output-Voltage Accuracy Over Load, Line, and Temperature
• Operates from 2.4V to 3.6V Supply
• Adjustable Output from 0.6V to (0.9 x VIN)
• Adjustable Soft-Start Reduces Inrush Supply Current
• Factory-Trimmed 1MHz Switching Frequency
• Compatible with Ceramic, Polymer, and Electrolytic Output Capacitors
• Safe Startup into Prebias Output
