The LTM4631 dual 10A or single 20A µModule (power module) step-down regulator comes in a 1.91-mm LGA package measuring 16 mm x 16 mm footprint. Its compact footprint allows placement close to its load, such as an FPGA, while sharing one heat sink covering both. The thin package also permits the LTM4631 to mount on the backside of circuit boards, freeing space on the topside for components. The LTM4631 operates from 4.5V to 15V supplies and regulates an output voltage from 0.6V to 1.8V with ±1.5% maximum total dc output voltage error from -40°C to +125°C. Its two outputs operate 180° out-of-phase, each capable of delivering 10A or 20A when the outputs current share. Two devices can current share, delivering up to 40A while minimizing input and output ripple current. The device features output overcurrent foldback and overvoltage protection. The LTM4631 operates in temperatures from -40°C to +125°C. Pricing starts at $24.88 each/1,000. For more information, visit http://www.linear.com/product/LTM4631
