What are the key features of LTM4668AIY#PBF?
- Quad independent 1.5A output channels from a single 2.7 V to 17 V input supply, enabling multi-rail power sequencing in a single component
- Complete µModule integration includes inductors, capacitors, and PWM controller in one BGA package, minimizing PCB area and design complexity
- Current-mode PWM control architecture provides fast transient response and cycle-by-cycle current limiting for load protection
- RoHS-compliant BGA form factor with 2019 introduction date and long production lifecycle for industrial supply chain reliability
What is LTM4668AIY#PBF used for?
The LTM4668AIY#PBF is designed for multi-rail power supply designs in FPGAs, ASICs, DSPs, and communications equipment where four independent regulated outputs from a single input bus between 2.7 V and 17 V are required. Its compact BGA µModule format is ideal for space-constrained server blades, industrial embedded computing boards, and test-and-measurement instruments that demand low-noise, high-accuracy power delivery without extensive external passives.

Frequently Asked Questions
What input voltage range and output current capability does the LTM4668AIY#PBF support across its four channels?
The LTM4668AIY#PBF accepts an input voltage from 2.7 V to 17 V (nominal 12 V) and delivers up to 1.5 A per channel across four independent outputs, allowing simultaneous regulation of four separate voltage rails for FPGA core, I/O, memory, and auxiliary supplies from a single power bus.
How does the LTM4668AIY#PBF compare to discrete multi-channel switcher designs for a compact FPGA power supply?
Unlike discrete designs requiring separate inductors, capacitors, and controller ICs for each rail, the LTM4668AIY#PBF integrates all passive and active components for four 1.5 A channels in one BGA µModule, reducing PCB area significantly and eliminating hundreds of external components while maintaining regulated outputs across a 2.7 V to 17 V input range.
What protection features does the current-mode PWM architecture in the LTM4668AIY#PBF provide during overload conditions?
The LTM4668AIY#PBF current-mode PWM controller enforces cycle-by-cycle current limiting at 1.5 A per channel, preventing inductor saturation and protecting downstream loads during short-circuit or overload events, with the BGA package rated to handle sustained thermal loads over the full industrial operating temperature range.
