Applications
The LTC3255EMSE#PBF is designed to step down high-voltage industrial and telecom bus rails (up to 48 V) to regulated lower voltages without using inductors, making it ideal for noise-sensitive analog and mixed-signal circuits. Its adjustable 2.4 V to 12.5 V output range suits a wide array of point-of-load needs in process control equipment, instrumentation, and distributed power architectures. The charge pump topology eliminates magnetic component EMI concerns, simplifying compliance in sensitive measurement environments.

Frequently Asked Questions
How does LTC3255EMSE#PBF achieve voltage step-down without inductors and what are the efficiency implications?
The LTC3255EMSE#PBF uses a switched capacitor charge pump topology that transfers energy via capacitors at 500 kHz instead of magnetic inductors. While peak efficiency is highest at fixed integer conversion ratios, the adjustable mode covering 2.4 V to 12.5 V output allows it to serve diverse loads from a 4 V to 48 V input, with significantly reduced EMI compared to inductive designs.
What input voltage range makes LTC3255EMSE#PBF suitable for 48 V telecom power architectures?
With a maximum input voltage of 48 V, the LTC3255EMSE#PBF can directly convert standard 48 V telecom bus rails down to regulated outputs between 2.4 V and 12.5 V. This eliminates the need for an intermediate bus converter in many designs, reducing power conversion stages and improving overall system efficiency in telecom and networking equipment.
Which package does LTC3255EMSE#PBF use and how does it help in space-constrained industrial designs?
This regulator is housed in a 10-pin MSOP package, one of the smallest small-outline footprints available for power ICs. The combination of 10 pins in the MSOP body and the absence of external inductors means the total solution footprint on the PCB is very small, making the LTC3255EMSE#PBF an excellent choice for compact instrumentation and process control modules operating from 4 V to 48 V rails.
