Dual 13 A/Single 26 A µModule Regulators Deliver 100 Amps

LTM4620-A_1Designed by Linear Technology, the LTM4620 is a dual 13 A per output or single 26 A output dc/dc µModule step-down regulator that delivers up to 100 A when four devices are current shared. The device is a complete dc/dc regulator system in a 15 x 15 x 4.41 mm LGA package, including inductors, power stages and all control circuits. With 200 LFM air flow, 12 VIN to 1.0 VOUT and at full load of 26A, the regulator's internal temperature rises only 60°C above ambient, and only 40°C with an external heat sink added to the top of the package. The regulator is designed to convert 5 V to 12 V inputs to high power, low voltage point-of-load system rails such as 2.5 V to as low as 0.6 V. Applications include mezzanine boards such as ATCA and microTCA systems, point-of-load regulation, ASICs, 28 nm FPGAs and SERDES. Rated for operation from -40°C to 125°C, pricing for the LTM4620 regulator system starts at $29.99 each/1,000.
