Linear Technology has introduced the LTM4628 µModule regulator containing two step-down 8 A DC/DC converter circuits with the inductors, MOSFETs and other necessary components in a LGA package.
The low thermal impedance of the package and high operating efficiency enable full output power DC/DC conversion from 12 IN to 1 VOUT at 70°C ambient with no air flow, or 86°C ambient with 30 m per min.
The device is designed to convert supply voltages ranging from 4.5 to 26.5 to two lower-output voltages ranging from 5.5 to 0.6 V with a total DC output error of ±1.5% including line and load regulation.
Each output delivers up to 8 A. The regulator’s PCB footprint and reduced design time provide a compact, low height, point-of-load regulator for applications such as data storage, routers, network switches, industrial automation, avionics and medical equipment.
The device has an internal clock for multiphase operation, beneficial for reducing the required bulk capacitance. In addition, it incorporates an onboard temperature diode, allowing users to monitor internal temperature.
Tracking and margining capabilities simplify supply sequencing and voltage modification in complex systems where various voltage rails are required.
