The LTM®4633 μModule® (micromodule) regulator combines three complete 10A switching mode DC/DC converters into one small package. Included in the package
are the switching controllers, power FETs, inductors, and
most support components. The LTM4633’s three regulators operate from 4.7V to 16V input rail(s) or 2.375V to
16V with an external 5V bias. The VOUT1 and VOUT2 output
range is 0.8V to 1.8V, while the VOUT3 output range is 0.8V
to 5.5V. Each output is set by one external resistor.
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 parallel operation
of VOUT1 and VOUT2, soft-start and output voltage tracking
for supply rail sequencing.
Fault protection features include overvoltage protection,
overcurrent protection and temperature monitoring. The
power module is offered in a space saving, thermally
enhanced 15mm × 15mm × 5.01mm BGA package. The
LTM4633 is RoHS compliant with Pb-free finish.
