LTM4630 - Dual 18A or Single 36A DC/DC μModule Regulator

Product Description

Linear Technology Corporation introduces the LTM4630, a dual 18A per output or single 36A output DC/DC μModule step-down regulator capable of delivering up to 144A when four devices are current shared.
The LTM4630 is a complete DC/DC regulator system in a 16mm x 16mm x 4.41mm LGA package, which includes inductors, MOSFETs, DC/DC controller and compensation circuitry. High efficiency and low thermal package impedance are achieved with expert analogue and packaging design. The efficiency for 36A at 1VOUT, from 12VIN is 86% and from 5VIN, is 88%.

With no need for an external heat sink, the LTM4630 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.

The excellent heat dissipation, scalable and high output power capability, small footprint and low profile package of the LTM4630 enable system designers to lay out more densely populated boards.

Applications

Telecom and Networking Equipment, Storage and ATCA Cards, Industrial Equipment.

Dimensions

16mm x 16mm x 4.41mm LGA and 16mm x 16mm x 5.01mm BGA Packages.

Other features

The device supports frequency synchronisation, multi-phase operation, Burst Mode operation and output voltage tracking for supply rail sequencing and has an onboard temperature diode for device temperature monitoring. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
