DC/DC uModule regulator delivers dual 8-A outputs from up to 26.5 VIN
November 29, 2010 // Paul Buckley
Linear Technology Corporation introduces the LTM4628, µModule regulator containing two step-down 8 A DC/DC converter circuits with the inductors, MOSFETs and other necessary components in a 15mm x 15 mm x 4.32 mm LGA package. The low thermal impedance of the LGA package and high operating efficiency enable full output power DC/DC conversion from 12 VIN to 1 VOUT at 70 degrees C ambient with no air flow, or 86 degrees C ambient with 200 linear feet per minute.
The LTM4628 is designed to convert supply voltages ranging from 4.5 V to 26.5 to two lower output voltages ranging from 5.5 V down to 0.6 V with an impressive total DC output error of ±1.5% including line and load regulation. Each output delivers up to 8 A. The LTM4628's tiny PCB footprint and reduced design time provide a compact, low height, quick to market point-of-load regulator solution for applications such as data storage, routers, network switches, industrial automation, avionics and medical equipment.
The LTM4628 has an internal clock for multiphase operation, beneficial for reducing the required bulk capacitance. In addition, this dual µModule regulator 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.
Availability and Pricing
The LTM4628 is rated for operation from -40 to 125 degrees C, priced at $19.90 each in 1000-piece quantities. All versions are available from stock.
