产品信息
The LTM®4624 is a complete 4A 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 14V or 2.375V to 14V with an external bias supply,
the LTM4624 supports an output voltage range of 0.6V to
5.5V, set by a single external resistor. Its high efficiency
design delivers 4A continuous, 5A peak, output current.
Only bulk input and output capacitors are needed.
The LTM4624 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 LTM4624 is available with SnPb (BGA) or RoHS
compliant terminal finish.
