Step-Down Regulator Optimized for Low VIN to Low VOUT Conversion
Linear Technology Corp.

The LTM4639 20A, dc/dc step-down μModule regulator converts 2.5V to 7V main-power system rails to point-of-load voltages as low as 0.6V with 88% efficiency. Applications include cloud-based equipment and RAID systems where 3.3V is preferred as the main power distribution rail. The device is housed in a 4.92-mm high BGA package with a 15 mm x 15 mm footprint. For 3.3V input to 1.5V output conversion at 20A load, efficiency is 88%, power loss is 3.9W, and junction temperature rise above ambient temperature is +37°C. Pricing is $19.45 each/1,000.
