What are the key features of LTM4668EY#PBF?
- Quad-output DC/DC µModule regulator delivering 1.5 A per channel from a 2.7 V to 17 V input supply
- Integrated magnetics and power MOSFETs in a compact BGA-49 package minimizing external component count and PCB area
- Current-mode pulse-width modulation control for fast transient response and excellent line and load regulation across all 4 outputs
What is LTM4668EY#PBF used for?
The LTM4668EY#PBF is ideal for powering multi-rail FPGAs, ASICs, and DSP systems in communications, industrial, and embedded computing platforms where board space is limited. Its quad-output architecture enables a single package to supply up to 4 independent voltage rails simultaneously, reducing BOM complexity on dense PCB designs. The wide 2.7 V to 17 V input range accommodates 5 V, 12 V, and battery-backed supply rails common in telecom and data center equipment.

Frequently Asked Questions
How many output channels does the LTM4668EY#PBF support, and what is the current rating per channel?
The LTM4668EY#PBF provides 4 independent output channels, each rated for 1.5 A continuous output current. This allows simultaneous regulation of up to 4 voltage rails from a single 2.7 V to 17 V input supply, making it well-suited for multi-rail FPGA and processor power trees.
What package does the LTM4668EY#PBF use, and what integration does it offer over discrete designs?
The LTM4668EY#PBF uses a BGA-49 µModule package that integrates the inductors, power MOSFETs, and PWM controller in one component. This eliminates the need for 4 separate inductors and sets of external FETs, reducing PCB area by up to 60% compared to an equivalent discrete quad-channel buck converter design.
Which input voltage range does the LTM4668EY#PBF cover, and how does it suit 12 V bus designs?
The LTM4668EY#PBF accepts input voltages from 2.7 V to 17 V, with 12 V as the nominal operating point. This range directly supports 12 V bus architectures common in data center servers and telecom blades, where all 4 outputs can be independently programmed to supply core, I/O, and auxiliary rails for ASICs or FPGAs.
When is the LTM4668EY#PBF a stronger choice than using four separate LTM4601 regulators?
For designs requiring 4 rails at up to 1.5 A each from a 12 V bus, the LTM4668EY#PBF integrates all 4 regulators in one BGA-49 footprint, occupying roughly one-quarter the PCB area of four individual LTM4601 devices. The quad-channel integration also simplifies layout, reduces bypass capacitor count, and consolidates thermal management into a single land pattern.
