Product details
Overview
LTM8060IY from Analog Devices is a quad-channel, 40V-input Silent Switcher μModule® regulator delivering up to 3A continuous (4A peak) per channel. It integrates controllers, MOSFETs, inductors, and support components in a single BGA package. With configurable output array capability, it supports 0.8V–8V outputs, 200kHz–3MHz switching frequency, and operates across –40°C to 125°C for industrial power rails in medical equipment and automated test systems.
For engineers reviewing the LTM8060IY datasheet, LTM8060IY pinout, LTM8060IY application, or LTM8060IY equivalent, this page delivers verified specifications, thermal performance data (θJC_bottom = 1.8°C/W), parallel configuration guidance, EMI-compliant layout notes, and validated alternatives for multi-rail power system design.
Technical Context
The LTM8060IY implements four independent current-mode PWM controllers with integrated power switches and shielded inductors. Each channel features programmable soft-start via TRSS pins, open-drain power-good (PG) monitoring, and selectable Burst Mode or forced continuous operation via SYNC pins.
It supports multiphase synchronization through CLKOUT12/CLKOUT34 outputs and external clock injection on SYNC12/SYNC34. Input voltage domains are split: VIN1 powers channels 1 & 2 (min 3V), VIN2 powers channel 2 only (min 2V), and VIN34 powers channels 3 & 4 (min 3V), enabling flexible rail sequencing and fault isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN1/VIN34: 3V–40V; VIN2: 2V–40V - enables wide-range industrial input compatibility and rail-flexible sequencing |
| Output Voltage Range | 0.8V–8V per channel - set by single FB resistor; supports core logic, FPGA I/O, and analog subsystems |
| Output Current | 3A continuous / 4A peak per channel at 12VIN, 3.3VOUT, TA = 60°C - derates with ambient temperature and airflow |
| Switching Frequency | 200kHz–3MHz - set by RT-to-GND resistor; higher frequencies reduce inductor size but increase switching loss |
| Thermal Resistance | θJC_bottom = 1.8°C/W - enables high-power density PCB layouts with bottom-side thermal vias to internal ground plane |
| EMI Compliance | CISPR 22 Class B & CISPR 25 Class 5 - achieved via Silent Switcher architecture without external shielding or ferrites |
| Operating Temperature | –40°C to 125°C junction - qualified for harsh environments including industrial controls and medical diagnostics |
Pinout & Package
The LTM8060IY is housed in a 165-pin, 16mm × 11.9mm × 3.32mm over-molded BGA package with RoHS-compliant SAC305 ball finish (MSL Level 4). Thermal performance relies on bottom-side GND pads (Bank 2) and proper PCB copper area/via design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1, VIN2, VIN34 | Channel input power rails | VIN1 powers CH1/CH2 control; VIN2 dedicated to CH2; VIN34 powers CH3/CH4 - enables independent input domain management |
| VOUT1–VOUT4 | Regulated output terminals | Each connects directly to output capacitor and load; supports paralleling via SHARE pins for up to 12A total |
| FB1–FB4 | Feedback reference node | Regulated to 800mV ±1%; sets output voltage via external resistor divider (RFB = 249k × (VOUT/0.8 − 1)) |
| RUN1–RUN4 | Channel enable inputs | Active-high logic; tie to respective VINn if always-on; use resistor divider for programmable undervoltage shutdown |
| SYNC12/SYNC34 | Sync input / mode control | Ground for Burst Mode; 2.8–4V for spread-spectrum forced continuous; external clock for phase synchronization |
| SHARE1–SHARE4 | Current-sharing control | Tie together when paralleling same-channel outputs or across multiple LTM8060 modules for balanced load sharing |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Silent Switcher architecture | Reduces radiated EMI by >30dB vs conventional μModules - eliminates need for external EMI filters in Class B/CISPR 25 designs |
| Configurable 3A output array | Four independent channels can be paralleled (e.g., CH1+CH2 = 6A) or operated at different voltages - supports mixed-voltage SoC/FPGA power trees |
| Low thermal resistance (θJC_bottom = 1.8°C/W) | Enables >6A total output in 16mm × 11.9mm footprint without heatsink - ideal for space-constrained industrial PCBs |
| Programmable soft-start & tracking | TRSS pins accept external capacitor or voltage source to control output ramp rate or sequence multiple rails - prevents inrush and ensures safe boot |
| Burst Mode efficiency optimization | Quiescent current <8mA at no load; maintains >85% efficiency down to 10mA load - extends battery life in standby-sensitive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-output DC/DC regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTM8061IY#PBF | Single-channel 3A variant; identical package, pinout, and feature set per channel | Used where only one regulated rail is needed; lacks multi-channel coordination features (SHARE, SYNC12/34) | Select LTM8061IY when designing modular power with discrete rail scaling instead of integrated quad solution |
| LTM4644IY#PBF | Quad 3A part with lower max input (14V), no Silent Switcher, higher quiescent current (12mA) | Suitable for low-voltage computing applications; lacks CISPR 25 compliance and bottom-thermal path optimization | Choose LTM4644IY only for cost-sensitive 12V-input systems where EMI filtering is already implemented externally |
Compared with LTM8060IY, the LTM8061IY offers channel-level flexibility but requires four separate footprints for quad-rail designs, while the LTM4644IY trades EMI performance and thermal efficiency for lower BOM cost in benign electrical environments.

FAQ
What is the maximum total output current achievable with the LTM8060IY?
The LTM8060IY supports up to 12A total continuous output (16A peak) when all four channels are paralleled using the SHARE pins. Derating applies based on ambient temperature, airflow, and PCB thermal design - at 75°C ambient with 0LFM, maximum total load is ~10A per DC2820A demo board data. Individual channel current is limited by junction temperature, not just package rating.
How does the LTM8060IY achieve CISPR 25 Class 5 compliance?
The LTM8060IY achieves CISPR 25 Class 5 compliance through its Silent Switcher architecture: symmetrical copper layout, integrated shielded inductors, and optimized internal current-loop minimization. Measured radiated emissions on the DC2820A demo board fall >10dB below the Class 5 peak limit at 14V input, 5V output, and 12A total load - no external ferrites or metal shields required.
Can the LTM8060IY operate with different output voltages on each channel?
Yes, the LTM8060IY supports independent output voltages from 0.8V to 8V per channel, set by individual FB resistor dividers. Each channel's feedback network connects to its dedicated FB pin (FB1–FB4), allowing simultaneous generation of 1.2V, 1.8V, 3.3V, and 5V rails - essential for powering heterogeneous SoCs and mixed-signal ASICs.
What is the role of the BIAS12 and BIAS34 pins on the LTM8060IY?
The BIAS12 and BIAS34 pins allow the LTM8060IY to draw bias power from an external source (e.g., VOUT) instead of VIN, improving efficiency when output voltage ≥3.3V. When tied to VOUT, the internal bias regulator switches from VIN1/VIN34, reducing input current and conduction loss - particularly beneficial in high-current, low-VIN applications like 5V-to-3.3V conversion.
Does the LTM8060IY require external components beyond input/output capacitors?
No - the LTM8060IY requires only bulk input and output capacitors for full operation. All power switches, inductors, controllers, and compensation networks are fully integrated. External components are limited to: (1) input/output ceramic capacitors (per Table 1), (2) FB resistors for voltage setting, (3) RT resistors for frequency selection, and optionally (4) TRSS capacitors for soft-start - no external diodes, drivers, or loop compensation needed.
