Product details
Overview
LTC7130EY#PBF from Analog Devices is a monolithic synchronous step-down DC/DC converter delivering up to 20A continuous output current with ultralow-DCR current sensing, ±0.5% output voltage regulation accuracy, and programmable switching frequency from 250kHz to 770kHz. It integrates high-speed differential remote sense amplification, DCR temperature compensation, and EXTVCC support for reduced power dissipation - optimized for high-efficiency, high-power-density FPGA/DSP core rails.
For engineers reviewing the LTC7130EY#PBF datasheet, LTC7130EY#PBF pinout, LTC7130EY#PBF application, or LTC7130EY#PBF equivalent, key selection considerations include its 63-pin BGA package (6.25mm × 7.5mm × 2.22mm), 4.5V–20V input range, 0.6V reference with tight tolerance, and precise 10mV–30mV programmable current limit threshold.
Technical Context
The LTC7130EY#PBF employs Analog Devices' proprietary current-mode architecture with dual-sense inputs (SNSD+, SNSA+) to enhance signal-to-noise ratio for sub-1mΩ DCR inductor sensing, reducing switching jitter and enabling stable operation at very low sense voltages. Its integrated differential remote sense amplifier (DIFFP/DIFFN → DIFFOUT) provides 0.997–1.003 V/V gain and 90dB PSRR, supporting accurate load-point regulation.
Control logic includes three selectable light-load modes (Burst Mode®, pulse-skipping, forced CCM) via MODE/PLLIN pin configuration, plus independent soft-start (TK/SS), tracking, and fault detection (PGOOD, UV/OV). The ITH pin serves as both error amplifier output and current comparator threshold reference, tightly coupling voltage and current loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 20V - supports wide bus voltages including 5V, 12V, and 19V battery systems without external regulators. |
| Output Current | Up to 20A continuous - enables single-chip core supply for high-performance FPGAs and ASICs. |
| Reference Voltage | 0.6V ±0.5% - ensures ≤±3mV absolute output voltage error across temperature and line/load conditions. |
| Switching Frequency | 250kHz to 770kHz programmable - allows optimization of efficiency vs. size trade-offs using standard 0.25µH inductors. |
| Current Sense Threshold | 10mV to 30mV programmable via ILIM pin - sets precise output current limit without external resistors or shunts. |
| DCR Temp Compensation | Enabled via ITEMP pin with NTC thermistor - maintains constant current limit over –40°C to 125°C junction range. |
| Package | 63-pin BGA, 6.25mm × 7.5mm × 2.22mm - compact footprint with thermal performance θJC = 10°C/W for high-power density layouts. |
Pinout & Package
63-pin BGA package (6.25mm × 7.5mm × 2.22mm) with SnPb/RoHS-compliant SAC305 finish, MSL Level 3, –40°C to 125°C operating junction temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (E4,E5,E6,E7,F4,F5,F6,F7,G7) | Main power input connection | High-current path to internal NMOS switches; requires local bulk capacitance (CIN) tied to PGND. |
| SW (G1,G2,G3,H1,H2,H3,J1,J2,J3) | Switch node | Connects to inductor and internal MOSFETs; high dv/dt node requiring minimized loop area and ground stitching. |
| BOOST (F1) | Bootstrap supply for top gate driver | Drives floating gate of upper NMOS; requires external bootstrap capacitor and Schottky diode. |
| INTVCC (D1) | Internal 5.5V regulator output | Powers control circuitry; must be decoupled with ≥4.7µF low-ESR capacitor to PGND. |
| EXTVCC (D7) | External bias supply input | Enables bypass of internal LDO when >4.7V applied - reduces power loss and heat generation. |
| SNSD+, SNSA+, SNS– | Dual-path DCR current sensing inputs | SNSD+ handles DC component; SNSA+ handles AC ripple; combined processing improves SNR by 14dB. |
| DIFFP, DIFFN, DIFFOUT | Differential remote sense amplifier | Measures true load voltage drop across output capacitor; enables <1% load regulation at point-of-load. |
| ITH (A5) | Error amplifier output / current threshold | Directly sets peak inductor current; also used for loop compensation and soft-start control. |
| VFB (A6) | Feedback input | Compares regulated output voltage (via DIFFOUT/resistive divider) against 0.6V reference. |
| RUN (B6) | Enable/disable control | 1.22V turn-on threshold with 80mV hysteresis; internal 1µA pull-up simplifies sequencing. |
| TK/SS (B5) | Soft-start and tracking input | 1.25µA internal charge current ramps external capacitor; supports voltage tracking with other rails. |
| ILIM (C2) | Current limit programming | DC voltage input (0V to INTVCC) selects 10/15/20/25/30mV sense threshold in 5mV steps. |
| ITEMP (D6) | DCR temperature compensation input | Connects to NTC thermistor near inductor; disables compensation if floated or tied to INTVCC. |
| MODE/PLLIN (C6) | Light-load mode selection / sync input | Ground = forced CCM; INTVCC = pulse-skipping; float = Burst Mode®; external clock = synchronization. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow-DCR current sensing | Supports inductors with DCR ≤0.37mΩ while maintaining SNR sufficient for stable 20A regulation - eliminates need for power-wasting shunt resistors. |
| Differential remote sense amplifier | 0.997–1.003 V/V gain, 2mV offset, 90dB PSRR - delivers <±0.5% load regulation even with 100mΩ PCB trace resistance between IC and load. |
| Programmable current limit | Five discrete thresholds (10/15/20/25/30mV) set via single ILIM pin voltage - enables precise overcurrent protection without external components. |
| DCR temperature compensation | Adjusts current limit in real time using NTC thermistor on ITEMP pin - maintains ±1% current accuracy from –40°C to 125°C. |
| EXTVCC power option | Bypasses internal 5.5V LDO when external ≥4.7V supply is present - reduces quiescent power dissipation by >50% in high-input-voltage applications. |
| Three light-load operating modes | Selectable via MODE/PLLIN: Burst Mode® (highest light-load efficiency), pulse-skipping (low noise), or forced CCM (lowest output ripple). |

FAQ
What is the maximum continuous output current supported by the LTC7130EY#PBF?
The LTC7130EY#PBF supports up to 20A continuous output current under typical thermal conditions (e.g., DC2341A demo board, 200LFM airflow). Derated maximum load current depends on ambient temperature, input/output voltage, and cooling - e.g., 15A at 85°C ambient with VIN=12V, VOUT=1.5V, and no heatsink.
Does the LTC7130EY#PBF require an external current sense resistor?
No, the LTC7130EY#PBF uses ultralow-DCR inductor sensing via SNSD+ and SNSA+ pins and does not require an external shunt resistor. It achieves high-accuracy current measurement by amplifying the inductor's inherent DCR voltage drop with built-in SNR enhancement and temperature compensation.
How is output voltage accuracy maintained across temperature and load for the LTC7130EY#PBF?
The LTC7130EY#PBF guarantees ±0.5% output voltage regulation accuracy over –40°C to 125°C via a precision 0.6V reference and high-gain differential remote sense amplifier (DIFFP/DIFFN → DIFFOUT). Load regulation is <0.1% due to servo-loop feedback that actively corrects for trace IR drops.
Can the LTC7130EY#PBF operate with a 5V input supply?
Yes, the LTC7130EY#PBF supports 4.5V–20V input. At VIN ≤5.5V, SVIN must be tied to INTVCC per datasheet Note 3. Input quiescent current is ~3.8mA at 5V, and efficiency exceeds 92% at 1.5V/10A output with appropriate inductor selection.
What thermal management features does the LTC7130EY#PBF include?
The LTC7130EY#PBF includes DCR temperature compensation (via ITEMP pin), thermal derating curves in the datasheet, and a low-thermal-resistance BGA package (θJC = 10°C/W). It also supports EXTVCC to reduce die self-heating and features a dedicated thermal pad (GND balls) for PCB copper pour attachment.
