Applications
The LTM8053EY#PBF is designed for industrial automation, communications infrastructure, and test-and-measurement equipment that requires a compact, low-EMI 3.5A step-down regulator from 24V or 28V bus voltages. Its 40V input range and Silent Switcher topology make it ideal for point-of-load conversion on factory automation PCBs and avionics where conducted emissions must meet strict CISPR or MIL-STD standards. The adjustable 0.97V to 15V output also suits FPGA core and I/O rail generation from a single 12V supply in space-constrained embedded computing modules.

Frequently Asked Questions
What is the maximum input voltage the LTM8053EY#PBF can handle and which industrial bus voltages does this cover?
The LTM8053EY#PBF accepts input voltages from 3.4V to 40V, covering standard industrial rails including 5V, 12V, 24V, and 28V. This wide range allows a single design to be powered from 24V factory automation buses and 28V avionics or vehicle power rails while stepping the voltage down to regulated 1.8V, 3.3V, 5V, or any value between 0.97V and 15V.
How does the Silent Switcher architecture of the LTM8053EY#PBF reduce EMI compared to conventional buck regulators in industrial enclosures?
The Silent Switcher architecture uses matched return current paths and a proprietary internal layout that cancels magnetic dipole radiation from the switching node. This reduces peak EMI by 10–20 dB compared to conventional buck converters at 3.5A output, enabling the LTM8053EY#PBF to pass CISPR 22 Class B conducted and radiated emissions limits without external shielding cans or large ferrite beads in 12V to 5V step-down applications.
For a 24V to 3.3V conversion at 3.5A in an industrial IoT gateway, what external components does the LTM8053EY#PBF require?
Because the LTM8053EY#PBF is a µModule regulator with an integrated inductor, power MOSFETs, bootstrap capacitor, and compensation network inside its BGA package, the designer needs only two output resistors to set the 3.3V output voltage, an input bulk capacitor of approximately 10 µF at 50V, and an output filter capacitor of approximately 22 µF to achieve stable 3.5A operation from a 24V input — reducing external component count to fewer than 10 parts.
