The LTM®4649 is a complete 10A high efficiency switching
mode step-down DC/DC μModule® regulator in a 9mm ×
15mm × 4.92 BGA package. Included in the package are the
switching controller, power FETs, inductor, and all support
components. Operating over an input voltage range of 4.5V
to 16V, the LTM4649 supports an output voltage range of
0.6V to 3.3V, set by a single external resistor. This high
efficiency design delivers 10A continuous current. Only
bulk input and output capacitors are needed.
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, programmable multiphase
operation, and output voltage tracking for supply rail
sequencing.
Fault protection features include output overvoltage and
overcurrent protection. The LTM4649 is offered in a small
9mm × 15mm × 4.92mm BGA package available with SnPb
or RoHS compliant terminal finish.
