LTM®4636 40 A μModule® Regulator

Analog Devices' LTM4636 40 A μModule regulator offers enhanced efficiency and thermal performance

Image of Analog Devices' LTM4636 μModule RegulatorAnalog Devices LTM4636 is a 40 A μModule (micromodule) stepdown regulator. It contains a switching controller plus power MOSFETs, inductor, and components supporting internal and external compensation. Its stacked inductor construction and high performance electrical design allow for a 12 VIN to 1 VOUT conversion at 40 A with 88% efficiency resulting in only 40°C rise with 200 LFM airflow and no power derating up to 85°C. The device operates from a 4.7 V to 15 V input supply and regulates an output from 0.6 V to 3.3 V set by an external resistor.  Current mode operation allows precise current sharing of up to six LTM4636 regulators to obtain a 240 A output. The LTM4636 is offered in a thermally enhanced 16 mm x 16 mm x 7.07 mm BGA package. The LTM4636 is RoHS-compliant.
