DC/DC regulator delivers 144A from 16 x 16mm package
A new µModule step down regulator has been unveiled by Linear Technology that is capable of delivering up to 144A when four devices are current shared.
The LTM4630 is a dual 18A per output or single 36A output complete dc/dc regulator system in a 16 x 16 x 4.41mm LGA package, which includes inductors, mosfets, dc/dc controller and compensation circuitry.
Optimised for excellent heat dissipation, high output power capability and low thermal package impedance, the device delivers 36A up to 60°C ambient with no airflow, 65°C with 200LFM and 69°C with 400LFM.
An external heat sink increases the maximum operating ambient temperature by approximately 10°C. Linear says the module enables system designers to lay out more densely populated boards.
Typical applications include mezzanine boards such as ATCA, µTCA, point of load regulation for new processors, asics and 28nm fpgas.
