    This application note provides an extensive guideline for the thermal performance of the LTM4601 μModule. The LTM4601 is characterized with and without heatsinking over an extended operating temperature range. De-rating curves are derived with the different heatsinking types, and the equivalent θJA (thermal resistance) is derived. The different θJA parameters are tabulated with reference to the different test conditions.

    In a recent discussion with a system designer, the re- quirement for his power supply was to regulate 1.5V and deliver up to 40A of current to a load that consisted of four FPGAs. This is up to 60W of power that must be delivered in a small area with the lowest profile (height) possible to allow a steady flow of air for cooling. The power supply had to be surface mountable and operate at high enough efficiency to minimize heat dissipation. He also demanded the simplest possible solution so his time could be dedicated to the more complex tasks. Aside from precise electrical performance, this solution had to remove the heat generated during DC to DC conversion quickly so that the circuit and the ICs in the vicinity do not over heat.

    In part one of this article, we discussed the circuit and electrical performance of a compact and low proп¬Ѓle 48A, 1.5V DC/DC regulator solution for a four-FPGA design. The new approach uses four DC/DC μModule™ regulators in parallel (Figure 1) to increase output current while sharing the current equally among each device. This solution relies on the accurate current sharing of these μModule regulators to prevent hot-spots by dissipating the heat evenly over a compact surface area. Each DC/DC μModule is a complete power supply with on-board inductor, DC/DC controller, MOSFETs, compensation circuitry and input/output bypass capacitors. It occupies only 15mm × 15mm of board area and has a low proп¬Ѓle (height) of only 2.8mm. This low proп¬Ѓle allows air to flow smoothly over the entire circuit. Moreover, this solution casts no thermal shadow on its surrounding components, further assisting in optimizing thermal performance of the entire system.
