element14 introduces Ultrathin Regulator from Linear Technology for ultra-dense data storage
Demo board enables fast response to load changes without compromising stability
element14 today announced the availability of the 3A Ultrathin Step-Down µModule Regulator, from Linear Technology Corporation, in an ultrathin 1.8mm profile LGA package with only a 6.25mm x 6.25mm footprint. With solder paste, the package height is less than 2mm, meeting the height restrictions of many PCIe (Peripheral Component Interconnect Express), Advanced Mezzanine Cards (AMC) for AdvancedTCA carrier cards in embedded computing systems.
The small size and low height allow the LTM4623 to be mounted on the backside of the PCB, freeing space on the topside for components such as memory and FPGAs. The LTM4623 operates from 4V to 20V input supplies and precisely regulates an output voltage from 0.6V to 5.5V with 1.5% maximum total DC output voltage error, Application examples include ultra-dense data storage, gateway controllers and 40Gbps to 100Gbps network equipment.
The LTM4623 solution fits in a 0.5cm² dual sided PCB or <1cm² on a singlesided PCB. The circuit only requires one input capacitor and one output capacitor, a resistor to set V, and a small capacitor for V tracking and softstart. With an auxiliary 5V bias, the LTM4623 operates from input supplies as low as 2.375V. The operating efficiency for converting 12V to 1.5V and 3.3V at 3A is 80% and 88%, respectively. Power loss for 12V to 1.5V is 1.1W, resulting in only a 24°C rise in junction temperature. The LTM4623 is rated for operation from 40°C to 125°C.
The 3A Ultrathin Step-Down µModule Regulator is available starting at $65.00 from Newark element14 in North America, Farnell element14 in Europe, and element14 in Asia Pacific.
