50A or Dual 25A µModule Regulator
MILPITAS, CA – February 29, 2016 – Linear Technology Corporation introduces the LTM4650,
a dual 25A or single 50A output step-down µModule® regulator with onboard shielded inductors,
MOSFETs and a dual DC/DC regulator IC housed in a small thermally enhanced plastic
package. The device is offered in a 16mm x 16mm x 5.01mm BGA with a patented built-in heat
sink. The heat sink, attached to the MOSFETs and inductors, rapidly moves heat from the
interior of the package to the top, where the surface of the heat sink is exposed to air. Thermal
dissipation is further improved with airflow, or a combination of airflow and attachment to an
external heat sink. With no external heat sink, the LTM4650 delivers 50A from 12VIN to 0.9VOUT
at up to 71°C ambient temperature with 200LFM airflow or up to 77°C with 400LFM.
The LTM4650’s precision current-mode architecture allows four devices to multiphase
current share, delivering up to 300A to loads such as ASICs, FPGAs and microcontrollers.
DC/DC conversion efficiency is improved by using Linear Technology’s DC/DC regulator IC
with strong gate drivers and low loss MOSFETs. Delivering 50A, 92% efficiency is recorded at
5VIN, 1.8VOUT and 86% at 12VIN, 1.0VOUT.
With a differential remote sense amplifier to compensate for voltage drop due to circuit
board trace impedance, the LTM4650 guarantees ±1.5% maximum total DC output voltage
accuracy over line, load and temperature.
The LTM4650 is rated for operation from –40ºC to 125ºC. The 1,000-piece price starts at
$46.75 each. For more information, visit www.linear.com/product/LTM4650.
