产品信息
The LTM®4625 is a complete 5A step-down switching
mode μModule (micromodule) regulator in a tiny 6.25mm
× 6.25mm × 5.01mm BGA package. Included in the package are the switching controller, power FETs, inductor and
support components. Operating over an input voltage range
of 4V to 20V or 2.375V to 20V with an external bias supply,
the LTM4625 supports an output voltage range of 0.6V to
5.5V, set by a single external resistor. Its high efficiency
design delivers up to 5A continuous output current. Only
bulk input and output capacitors are needed.
The LTM4625 supports selectable discontinuous mode
operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode
control enable a very fast transient response to line and
load changes without sacrificing stability.
Fault protection features include overvoltage, overcurrent
and overtemperature protection.
The LTM4625 is available with SnPb or RoHS compliant
terminal finish.
