6A, 28V
IN
DC/DC µModule
with PLL, Output Tracking
and Margining
The LT M
®
4603HV is a complete 6A step-down switch mode
DC/DC power supply with onboard switching controller,
MOSFETs, inductor and all support components. The
µModule
TM
is housed in a small surface mount 15mm ×
15mm × 2.82mm 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 efficiency design
delivers 6A continuous current (8A peak). Only bulk input
and output capacitors are needed to complete the design.
The low profile (2.82mm) 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
®
operation for high load currents.
A high switching frequency and adaptive on-time current
mode architecture deliver a very fast transient response
to line and load changes without sacrificing stability. An
onboard remote sense amplifier can be used to accurately
regulate an output voltage independent
of load current.
