Analog Devices’ Power by Linear LTM4653 is a 58-VIN
step-down µModule regulator that can safely operate from unregulated or
fluctuating 24-V to 48-V input supplies in noisy environments. Integrating
input and output filters enable the device to meet the EN55022 Class B EMC
standards, and the low EMI architecture makes it suitable for use in signal
processing applications.

output voltage is adjustable with one resistor from 0.5 V to 94% of VIN,
providing the ability to use one product to generate common system bus voltages
of 3.3 V, 5 V, 12 V, and 24 V. The LTM4653 houses a switching regulator
controller, power switches, inductor, and other supporting components in a 15 x
9 x 5.01-mm BGA package. Only the bulk input and output filter capacitors are
needed to complete the design. The LTM4653 operating temperature range is –40°C
to 125°C.
