产品信息
The LTM®4627 is a complete 15A output high efficiency
switch mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor
and compensation components. Operating over an input
voltage range from 4.5V to 20V, the LTM4627 supports an
output voltage range of 0.6V to 5V, set by a single external
resistor. Only a few input and output capacitors are needed.
Current mode operation allows precision current sharing
of up to four LTM4627 regulators to obtain 60A output.
High switching frequency and a current mode architecture
enable a very fast transient response to line and load
changes without sacrificing stability. The device supports
frequency synchronization, multiphase/current sharing
operation, Burst Mode operation and output voltage tracking for supply rail sequencing.
The LTM4627 is offered in thermally enhanced 15mm ×
15mm × 4.32mm LGA and 15mm × 15mm × 4.92mm BGA
packages. The LTM4627 is available with SnPb (BGA) or
RoHS compliant terminal finish.
