Product details
Overview
LMR36006FSCQRNXRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 0.6 A output current across a 4.2-V to 60-V input range, featuring 2.1-MHz fixed switching frequency, spread-spectrum modulation, and FPWM operation mode - deployed in ADAS camera modules for compact, low-EMI power rails.
For engineers reviewing the LMR36006FSCQRNXRQ1 datasheet, LMR36006FSCQRNXRQ1 pinout, LMR36006FSCQRNXRQ1 application, or LMR36006FSCQRNXRQ1 equivalent, key selection criteria include its HotRod™ VQFN-HR (12-pin) package with wettable flanks, ±1.5% reference voltage tolerance, 26-µA quiescent current in PFM, thermal shutdown at 170°C, and integrated power-good flag with 80–200-µs deglitch delay.
Technical Context
The LMR36006FSCQRNXRQ1 uses peak-current-mode control with internal loop compensation, enabling stable regulation from 20-V input to 5-V output at 2.1 MHz without external compensation components. Its FPWM mode ensures constant-frequency operation across all load conditions, eliminating audible noise and simplifying EMI filtering.
It integrates high-side and low-side MOSFETs (RDS(on) = 225–435 mΩ / 150–280 mΩ), supports precision enable with hysteresis (110 mV), and delivers true power-good status via open-drain PG pin with built-in filtering - all within a –40°C to +150°C junction temperature range compliant with automotive Grade 1 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2 V to 60 V - supports wide automotive battery transients including cold-crank (4.2 V) and load-dump (66 V absolute max). |
| Output Current | 0.6 A continuous - sufficient for powering image sensors, SerDes interfaces, and microcontrollers in camera ECUs. |
| Switching Frequency | 2.1 MHz (±10%) - enables use of small 1-µH inductors and reduces solution footprint versus 400-kHz variants. |
| Quiescent Current | 26 µA typical - maintains ultra-low standby power in always-on ADAS subsystems without compromising wake-up response. |
| Reference Voltage | 1.0 V ±1.5% - sets output accuracy for adjustable configurations; combined with FB pin leakage <0.2 nA, enables stable 1% output regulation. |
| Thermal Shutdown | 170°C shutdown / 158°C recovery - provides robust overtemperature protection during sustained high-load or poor PCB thermal design. |
| Power-Good Delay | 80–200 µs deglitch - prevents false system resets during brief line/load transients while ensuring reliable rail monitoring. |
| EMI Performance | CISPR-25 Class 5 compliant - achieved via HotRod™ package, parallel input path, and ±4% triangular spread spectrum. |
Pinout & Package
VQFN-HR (12-pin) package, 2.00 mm × 3.00 mm body size with wettable flanks - optimized for automated optical inspection (AOI) and low-inductance PCB layout in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 11 PGND | Power ground | Primary return path for high-current switch node; must be connected to AGND and CIN with short, wide copper traces to minimize ground bounce. |
| 2, 10 VIN | Main input supply | Accepts 4.2–60 V; connects directly to bulk input capacitor; requires low-ESR ceramic placement adjacent to pins 2/10. |
| 3 NC | No-connect | Internally unconnected; used on PCB to route CBOOT capacitor to SW pin - simplifies layout and reduces parasitic inductance. |
| 4 BOOT | Bootstrap supply | Drives high-side MOSFET gate; requires 100-nF X7R capacitor between BOOT and SW to sustain gate drive during high-duty-cycle operation. |
| 5 VCC | Internal 5-V LDO output | Supplies internal control circuitry; decoupled with 1-µF capacitor to AGND; can power PG pull-up but not external loads. |
| 6 AGND | Analog ground reference | Ground reference for FB, EN, PG, and internal references; isolated from PGND at single-point connection to reduce noise coupling. |
| 7 FB | Feedback input | Senses output voltage divider ratio; input bias current <0.2 nA enables high-resistance dividers without accuracy loss. |
| 8 PG | Open-drain power-good flag | Asserts high when VOUT is within 93–107% of target; requires external pull-up; remains valid down to 2-V input. |
| 9 EN | Enable control | Logic-level input with 1.157–1.231 V turn-on threshold and 110-mV hysteresis; supports direct VIN connection or precision UVLO via resistor divider. |
| 12 SW | Switch node | Connects to power inductor; high dv/dt node requiring minimized trace area and guard ring; routed adjacent to NC pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| HotRod™ flip-chip packaging | Reduces switch-node ringing and radiated EMI by minimizing bond-wire inductance - critical for CISPR-25 Class 5 compliance in camera modules. |
| FPWM + spread spectrum | Eliminates frequency harmonics through ±4% triangular dithering at 16-kHz rate, lowering peak emissions without sacrificing regulation stability. |
| Integrated power-good flag | Provides system-level rail monitoring with built-in 80–200-µs deglitch and automatic assertion during startup, fault, or EN deactivation. |
| Auto-recovery hiccup protection | Enters 94-ms shutdown cycle upon short-circuit detection (FB < 0.4 V), limiting average power dissipation and preventing thermal runaway. |
| Ultra-low IQ in PFM | 26-µA operating quiescent current enables >90% efficiency at 1-mA loads - essential for always-on vision processing subsystems. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with 150°C junction rating - meets functional safety requirements for ASIL-B systems. |

FAQ
What is the maximum input voltage rating for the LMR36006FSCQRNXRQ1?
The LMR36006FSCQRNXRQ1 has an absolute maximum input voltage rating of 66 V, with recommended operating range from 4.2 V to 60 V. This allows robust operation during automotive load-dump events and cold-crank conditions. The device incorporates input undervoltage lockout and internal LDO supervision to ensure safe startup and shutdown behavior across this full range. Always observe derating guidelines in TI's SNVSAY7D datasheet Section 7.1.
Does the LMR36006FSCQRNXRQ1 support fixed-output voltage configurations?
The LMR36006FSCQRNXRQ1 is configured for adjustable output voltage via the FB pin; however, TI offers pin-compatible fixed-output variants like LMR36006FSC3RNXRQ1 (3.3 V). The LMR36006FSCQRNXRQ1 itself requires an external resistor divider to set VOUT, supporting outputs from 1 V to ~58 V. Its ±1.5% reference voltage tolerance and sub-0.2-nA FB leakage ensure tight regulation accuracy across temperature and load.
How does the power-good (PG) flag behave during startup and fault conditions for the LMR36006FSCQRNXRQ1?
The LMR36006FSCQRNXRQ1 PG pin asserts high after a ~4-ms delay following EN activation, once VOUT reaches 93% of target. It goes low during thermal shutdown, current-limit hiccup, or EN deactivation. With built-in 80–200-µs deglitching, it ignores brief transients. PG remains valid down to 2-V input and can be pulled up to VCC or VOUT; if unused, it must be grounded per datasheet guidance.
What thermal performance can be expected from the LMR36006FSCQRNXRQ1 in a typical 2-layer PCB layout?
In a standard 2-layer board with 1-oz copper, 200 mm² exposed thermal pad connected to inner ground plane, the LMR36006FSCQRNXRQ1 achieves ~23.3°C/W junction-to-board thermal resistance (ψJB). At 0.6-A load and 24-V input, typical power dissipation is ~350 mW, resulting in ~8.2°C rise above board temperature. For sustained 150°C junction operation, ambient must remain ≤142°C - validated per AEC-Q100 Grade 1 requirements in TI's thermal characterization report.
Is the LMR36006FSCQRNXRQ1 compatible with WEBENCH® Power Designer?
Yes, the LMR36006FSCQRNXRQ1 is fully supported in TI's WEBENCH® Power Designer tool (version 22.1+). Users can generate complete schematics, bill-of-materials, efficiency plots, thermal simulations, and PCB layout recommendations - including optimized component selection for 2.1-MHz operation, spread-spectrum settings, and EMI filter design aligned with CISPR-25 Class 5 test limits. The tool validates performance across –40°C to +125°C ambient.
