Product details
Overview
LTM4613IY#PBF from Analog Devices (formerly Linear Technology) is an ultralow-noise, 8A, 36V-input DC/DC µModule regulator in a 15mm × 15mm × 4.92mm BGA package. It delivers precisely regulated 3.3V–15V output voltage with ±2% total DC error, supports EN55022 Class B EMI compliance, and features PLL synchronization, output margining, and fast transient response - deployed in RF power supplies and telecom base station power rails.
For engineers reviewing the LTM4613IY#PBF datasheet, LTM4613IY#PBF pinout, LTM4613IY#PBF application, or LTM4613IY#PBF equivalent, key selection criteria include input voltage range (5V–36V), output current capability (8A continuous), thermal performance at –40°C to 125°C, and compatibility with polyphase parallel operation for high-current systems.
Technical Context
The LTM4613IY#PBF integrates a constant on-time current-mode controller, power FETs, inductor, and support circuitry into a single BGA module. Its adaptive on-time architecture enables sub-100µs load transient settling time and stable operation with all-ceramic output capacitors.
Onboard input filtering and noise cancellation reduce conducted and radiated EMI, achieving EN55022B compliance without external shielding. Frequency synchronization via PLLIN allows phase interleaving across multiple units, while MARG0/MARG1/MPGM pins enable precise ±5% programmable output voltage margining with hardware-selectable polarity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5V to 36V DC - supports wide industrial and telecom input rails including 24V and 36V nominal systems. |
| Output Current | 8A continuous - sufficient for FPGA core rails, ASIC I/O banks, or RF transceiver bias supplies. |
| Output Voltage Range | 3.3V to 15V - set by single external resistor (e.g., 5.23kΩ for 12V), enabling flexible system-level voltage scaling. |
| Switching Frequency | 600kHz typical at 12VOUT - balances efficiency, size, and ripple; adjustable via fSET pin for noise-sensitive applications. |
| Total DC Output Error | ±2% maximum - includes line, load, and temperature effects; ensures reliable regulation under full operating conditions. |
| Operating Temperature | –40°C to 125°C junction - validated for industrial and avionic environments without derating at full 8A load. |
| EMI Compliance | EN55022 Class B - achieved with internal input filter and noise cancellation; eliminates need for external EMI filters in most designs. |
Pinout & Package
Package: 133-ball BGA, 15mm × 15mm × 4.92mm, RoHS-compliant SAC305 solder finish, MSL Level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Bank 1) | Power Input | Accepts 5V–36V input; requires local ceramic decoupling to PGND for RMS current handling and EMI suppression. |
| VOUT (Bank 3) | Power Output | Delivers regulated 3.3V–15V/8A; connects directly to load and bulk output capacitors (≥100µF recommended). |
| PGND (Bank 2) | Power Ground Return | Common return path for input and output currents; must be low-inductance plane tied to output capacitor ground. |
| VFB | Error Amplifier Inverting Input | Internally biased at 0.6V reference; external RFB sets output voltage per VOUT = 0.6V × (100k + RFB)/RFB. |
| TRACK/SS | Soft-Start & Tracking Control | Accepts soft-start capacitor for controlled ramp-up or resistor divider for supply sequencing with master/slave configurations. |
| MPGM, MARG0, MARG1 | Margining Interface | MPGM sets margin magnitude (via 1.18V/R); MARG0/MARG1 select up/down/no margin per truth table - enables production test voltage tolerance validation. |
| PLLIN | External Clock Sync Input | Accepts 2V–INTVCC clock signal; enables phase alignment for multiphase operation and harmonic reduction in dense PCB layouts. |
| RUN | Enable/Shutdown Control | Logic-high (>1.9V) enables regulation; logic-low (<1V) disables switching and reduces quiescent current to 50µA. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated µModule Architecture | Complete power solution - no external inductor, MOSFETs, or loop compensation required; reduces design cycle time and layout risk. |
| Ultralow Noise Operation | 19mVP-P output ripple at 12V/0A; achieves EN55022B radiated emission limits without ferrite beads or metal shields. |
| Programmable Margining | Hardware-based ±5% output adjustment via three pins - supports automated production testing and field calibration without firmware changes. |
| Fast Transient Response | 100µs settling time for 0%→50%→0% load steps at 12VOUT - maintains regulation during FPGA dynamic core switching or burst-mode RF transmission. |
| Parallel Current Sharing | Native current-mode control enables accurate load balancing across ≥2 modules - eliminates need for external current-sense amplifiers or droop resistors. |

FAQ
What is the maximum output current rating of the LTM4613IY#PBF under continuous operation?
The LTM4613IY#PBF is rated for 8A continuous output current at 12VOUT with 24V input and proper thermal management on a 4-layer PCB. Derating applies above 85°C ambient or with reduced airflow; full 8A is guaranteed across –40°C to 125°C junction temperature per datasheet Figure 15.
Does the LTM4613IY#PBF require external compensation components for stability?
No, the LTM4613IY#PBF includes fully integrated loop compensation. Its current-mode architecture and internal error amplifier eliminate the need for external compensation networks - only input and output bulk capacitors are required to complete the design.
How does the LTM4613IY#PBF achieve EN55022 Class B compliance without external filters?
The LTM4613IY#PBF achieves EN55022B compliance through integrated input filtering, noise cancellation circuitry, and optimized internal layout. These features suppress both conducted and radiated emissions - verified in standard test setups per Figure 7 of the datasheet - eliminating the need for external EMI filters in most implementations.
Can multiple LTM4613IY#PBF modules be paralleled for higher current, and how is current sharing ensured?
Yes, multiple LTM4613IY#PBF modules can be paralleled for higher current. Current sharing is inherently balanced via their current-mode control architecture - no external current-sense resistors or droop networks are needed. Phase synchronization via PLLIN further improves thermal distribution and reduces output ripple.
What is the purpose of the MARG0, MARG1, and MPGM pins on the LTM4613IY#PBF?
The MARG0, MARG1, and MPGM pins implement hardware-based output voltage margining on the LTM4613IY#PBF. MPGM sets margin magnitude (via resistor to ground), while MARG0/MARG1 select up/down/no margin per a defined truth table - enabling production test of system functionality across voltage tolerance bands without software intervention.
