Ultrathin µModule Power Products Ultrathin 1.82mm 20VIN µModule Regulators (www.linear.com/ultrathin) 4.41mm 1.82 mm The new family of ultrathin µModule® regulators (power modules) are 1.82mm tall and designed to fit on the backside of a PCB or under an FPGA or CPU heat sink. This family is designed for 3.3VIN, 5VIN and 12VIN power rails used in PCIe and similar cards. The short package profile (height) meets the height restriction of PCIe cards for mounting these devices on the backside of the PCB. Another unique advantage is that Ultrathin µModule regulators can be placed on a PCB very close to FPGAs or microcontrollers while sharing one heat sink (passive heat sink or liquid cooled cold plate) covering both the digital IC and the µModule regulator. HEAT SINK OR LIQUID COLD PLATE 2mm to 2.5mm PCB FPGA, MICROPROCESSOR, ASIC ULTRATHIN µMODULE REGULATOR An ultrathin µModule regulator’s package height is 1.8mm or <2mm, including PCB solder paste thickness. These compact DC/DC regulators can be placed very close to an FPGA, ASIC or microprocessor under a common heat sink.
