Product details
Overview
LV2862XLVDDCR from Texas Instruments is a 60-V input, 600-mA synchronous buck DC/DC converter in SOT-6L (DDC) package, featuring 770-kHz fixed switching frequency, 0.765-V feedback reference, and Eco-mode for ultra-low 28-µA light-load quiescent current. It delivers regulated output in industrial power supplies, motor drives, and grid infrastructure where wide VIN (4–60 V) and transient tolerance (65 V) are critical.
For engineers reviewing the LV2862XLVDDCR datasheet, LV2862XLVDDCR pinout, LV2862XLVDDCR application, or LV2862XLVDDCR equivalent, key selection criteria include its 96% max duty cycle, integrated boot diode, internal soft start, thermal shutdown at 170°C, and high-voltage enable input with 1.25-V turn-on threshold.
Technical Context
The LV2862XLVDDCR implements constant-frequency peak current mode control with internal slope compensation and leading-edge blanking to ensure stability across line/load transients. Its integrated high-side MOSFET features 900-mΩ on-resistance and is driven via an internal bootstrap regulator requiring external CB–SW capacitor.
Operation includes Eco-mode for sub-100-mA loads-reducing switching losses while maintaining regulation-and a dedicated SHDN pin with 60-V absolute max rating, internal pullup, and UVLO hysteresis (4 V rising / 3 V falling). The device uses internal compensation and requires no external loop components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 60 V - supports unregulated industrial rails and automotive battery systems with 65-V transient tolerance |
| Switching Frequency | 770 kHz - enables compact 22-µH inductor and low-profile 10-µF ceramic output capacitor |
| Output Current | 600 mA - sufficient for powering microcontrollers, sensors, and gate drivers in distributed power architectures |
| Feedback Voltage | 0.765 V - sets precise output voltage using standard resistor divider (e.g., 54.9 kΩ/10 kΩ for 5 V) |
| Quiescent Current | 28 µA in Eco-mode - extends battery life in always-on monitoring systems without sacrificing regulation |
| Max Duty Cycle | 96% - supports high VIN-to-VOUT ratios (e.g., 48 V → 5 V) while maintaining dropout operation |
| Thermal Shutdown | 170°C trip point with 10°C hysteresis - protects against sustained overload or poor PCB thermal design |
Pinout & Package
LV2862XLVDDCR is housed in a thermally enhanced TSOT-6L (DDC) package measuring 2.90 mm × 2.80 mm with exposed pad for improved heat dissipation. The 6-pin layout supports minimal board area and simplified routing in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CB | Bootstrap bias supply | Connects external 100-nF ceramic capacitor to SW; supplies gate drive voltage for internal high-side MOSFET |
| GND | Power ground reference | Primary return path for power stage and control circuitry; must be connected to low-impedance PCB ground plane |
| FB | Feedback input | Senses output voltage divider; regulates VOUT to 0.765 V reference with ±2.5% accuracy over temperature |
| SHDN | Enable/disable control | High-voltage tolerant input (60 V max); pulled up internally; <1.25 V disables regulator, drawing only 1 µA shutdown current |
| VIN | Main power input | Supplies internal bias and high-side FET drain; withstands 65-V transients per absolute maximum rating |
| SW | Switch node | Connects to inductor, Schottky diode cathode, and CB capacitor; carries high dv/dt and pulsed current |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode operation | Reduces switching frequency and gate drive activity below ~100 mA load, cutting IQ to 28 µA without compromising regulation |
| Integrated boot diode | Eliminates need for external bootstrap diode, reducing BOM count and layout complexity in high-duty-cycle designs |
| Internal soft start | Prevents inrush current during startup by ramping COMP node voltage; avoids output overshoot and input capacitor stress |
| Pulse-by-pulse current limit | Clamps peak switch current at 1200 mA to protect internal MOSFET during short-circuit or overload events |
| High-voltage enable input | Accepts logic or analog control signals up to 60 V, enabling direct interface with PLC I/O or industrial sensor outputs |
Applications
| Industrial Power Supply | Motor Drive Control |
|---|---|

IC Role / Device Role / Timing Role: Main system regulator delivering low-noise, thermally robust power under variable load conditions. Use Value: Internal compensation and soft start simplify compliance with IEC 61000-4-5 surge immunity; SOT-6L footprint saves space on crowded appliance PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMR16006XDDAR | 60-V, 600-mA, 600-kHz buck; higher 300-µA no-load IQ; no Eco-mode; requires external compensation | Lacks light-load efficiency optimization; less suitable for battery-backed or energy-sensitive systems | Choose when design prioritizes cost over light-load performance and layout flexibility allows external compensation network |
| TPS54202HDDCR | 42-V, 2-A, 2.1-MHz buck; higher current rating; integrated FETs; 15-µA IQ in Eco-mode; smaller 2.9-mm × 2.8-mm WSON | Better suited for higher-current, higher-frequency designs but limited to 42 V input and lacks 65-V transient rating | Prefer for compact, high-efficiency 12–24 V systems needing >600 mA; avoid where 48–60 V input or surge immunity is required |
Compared with LMR16006XDDAR and TPS54202HDDCR, LV2862XLVDDCR uniquely balances 60-V input capability, 65-V transient tolerance, 28-µA Eco-mode IQ, and fully integrated compensation in a proven SOT-6L package-making it optimal for ruggedized industrial and grid applications demanding reliability across wide voltage excursions.

FAQ
What is the maximum input voltage rating for LV2862XLVDDCR, and how does it handle transients?
The LV2862XLVDDCR has an absolute maximum input voltage rating of 65 V, allowing it to safely withstand short-duration transients beyond its 60-V operating range. This rating is validated per JEDEC standards and enables reliable operation in industrial environments with inductive switching noise or lightning-induced surges on DC distribution lines. The device remains functional and undamaged during these events without requiring external clamping circuitry.
Does LV2862XLVDDCR require external compensation components?
No, LV2862XLVDDCR integrates full Type II compensation within the IC, eliminating the need for external resistors or capacitors on the COMP pin. This simplifies design, reduces bill-of-materials count, and ensures consistent loop stability across temperature and manufacturing variance-critical for high-volume industrial deployments where layout reproducibility matters.
How does Eco-mode operate in LV2862XLVDDCR, and what is its impact on efficiency?
Eco-mode in LV2862XLVDDCR activates automatically at light loads (typically below ~100 mA), reducing switching frequency and gate drive activity to achieve a typical quiescent current of 28 µA. This cuts power loss significantly compared to forced PWM operation, improving light-load efficiency by up to 20 percentage points-enabling longer battery runtime in always-on monitoring systems powered by the LV2862XLVDDCR.
What is the function of the CB pin on LV2862XLVDDCR, and what capacitor value is recommended?
The CB pin on LV2862XLVDDCR provides gate drive voltage to the internal high-side MOSFET via a bootstrap capacitor connected between CB and SW. A 100-nF X7R/X5R ceramic capacitor rated for ≥10 V is recommended; larger values (up to 1 µF) improve gate drive margin in high-duty-cycle or low-VIN-to-VOUT ratio applications. This configuration eliminates the need for an external bootstrap diode.
Can LV2862XLVDDCR be used in automotive applications, and what qualifications does it meet?
LV2862XLVDDCR is not AEC-Q200 qualified and is not recommended for safety-critical automotive powertrain or ADAS applications. However, it is widely used in non-safety automotive subsystems such as body control modules, infotainment power rails, and telematics units where its 60-V input range, 65-V transient tolerance, and -40°C to +125°C operating junction temperature meet functional requirements-subject to system-level validation per ISO 16750.
