What are the key features of LTM4611IV#PBF?
- Fully integrated 15A DC/DC µModule with PWM controller, MOSFETs, inductor, and passives in a single 133-LGA package
- Adjustable output voltage from 0.8V to 5V covers most core and I/O supply rails for FPGAs, DSPs, and ASICs
- 1.5V to 5.5V input range supports direct operation from 1.8V, 2.5V, 3.3V, and 5V bus rails
- Current-mode control provides fast transient response and inherent cycle-by-cycle overcurrent protection
What is LTM4611IV#PBF used for?
The LTM4611IV#PBF is used in high-current FPGA core supply circuits, ASIC power rails, and multi-rail server board power delivery networks where 15A at a programmable voltage between 0.8V and 5V is required from a compact footprint. Its self-contained µModule construction eliminates inductor selection and PCB layout challenges, making it ideal for space-constrained telecom line cards, network switches, and test-and-measurement instruments.

Frequently Asked Questions
What input voltage range and maximum output current does the LTM4611IV#PBF support?
The LTM4611IV#PBF accepts input voltages from 1.5V to 5.5V and delivers up to 15A continuous output current. This input range covers standard 1.8V, 2.5V, 3.3V, and 5V bus rails, while the 15A output capacity is sufficient for powering high-current FPGA core supplies and multi-core processor I/O banks without external power discretes.
How is the output voltage of the LTM4611IV#PBF set, and what range is available?
Output voltage is programmed by a single external resistor connected to the VFB pin, allowing adjustment from 0.8V to 5V. This covers DDR memory termination at 0.9V, CPU core supplies at 1.0V to 1.2V, and general-purpose I/O rails at 1.8V, 2.5V, or 3.3V using standard 1% resistor values without modifying the internal compensation network.
What does the µModule format of LTM4611IV#PBF include, and how does it simplify PCB layout?
The LTM4611IV#PBF integrates the PWM controller, power MOSFETs, an output inductor, and most passive components within the 133-ball LGA package itself. This eliminates inductor footprint design, switch-node ringing mitigation, and gate-drive trace impedance concerns, reducing the external component count to a handful of input and output filter capacitors and the one feedback resistor.
For an FPGA design requiring a 1.0V core rail at 12A, how does LTM4611IV#PBF compare to a discrete buck converter solution?
The LTM4611IV#PBF delivers the required 1.0V at up to 15A with a board footprint of roughly 15 mm x 15 mm including bypass capacitors, whereas a discrete buck converter solution typically requires a 30 mm x 25 mm or larger area when the inductor, MOSFETs, gate driver, and passives are all considered. The µModule approach also reduces design time by weeks, since the internal loop compensation is pre-optimized at the factory.
