DESCRIPTIO
The LTM
DC/DC power supply with onboard switching controller,
MOSFETs, inductor and all support components. The
μModule
15mm × 2.8mm LGA package. Operating over an input
voltage range of 4.5 to 28V, the LTM4603HV supports an
output voltage range of 0.6V to 5V as well as output voltage
tracking and margining. The high effi ciency design deliv-
ers 6A continuous current (8A peak). Only bulk input and
output capacitors are needed to complete the design.
The low profi le (2.8mm) and light weight (1.7g) package
easily mounts on the unused space on the back side of
PC boards for high density point of load regulation. The
μModule can be synchronized with an external clock for
reducing undesirable frequency harmonics and allows
PolyPhase
A high switching frequency and adaptive on-time current
mode architecture deliver a very fast transient response
to line and load changes without sacrifi cing stability. An
onboard remote sense amplifi er can be used to accurately
regulate an output voltage independent of load current.
