Product details
Overview
LMR16006YDDCR from Texas Instruments is a 60 V input, 600 mA synchronous buck DC/DC regulator in SOT-6L package, featuring 2.1 MHz fixed-frequency current-mode control, 0.765 V feedback reference, and ECO mode for ultra-low 28 µA quiescent current-designed for industrial power conditioning and battery-powered instrumentation.
For engineers reviewing the LMR16006YDDCR datasheet, LMR16006YDDCR pinout, LMR16006YDDCR application, or LMR16006YDDCR equivalent, key selection criteria include its 2.1 MHz switching frequency enabling compact magnetics, high-duty-cycle operation down to 3 V CB–SW, integrated boot diode, and thermal shutdown at 170°C with 10°C hysteresis.
Technical Context
The LMR16006YDDCR implements peak current-mode control with internal slope compensation and a 2.1 MHz oscillator, supporting stable regulation across 4 V–60 V input while maintaining tight output accuracy via 0.765 V ±1.8% feedback reference. Its integrated high-side MOSFET (900 mΩ RDS(on)) and bootstrap refresh circuit enable up to 97% duty cycle in dropout conditions.
ECO mode activates automatically when inductor peak current falls below 80 mA, reducing switching losses and holding quiescent current at 28 µA-critical for battery systems. Overvoltage transient protection (OVTP) clamps FB > 108% of reference to suppress overshoot during load unload, and pulse-by-pulse current limiting caps peak switch current at 1.2–1.7 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 60 V - supports wide-range industrial and automotive inputs without pre-regulation. |
| Output Current | Up to 600 mA - sufficient for powering microcontrollers, sensors, and interface ICs in space-constrained designs. |
| Switching Frequency | 2.1 MHz (Y version) - enables use of <22 µH inductors and <10 µF ceramic output capacitors for minimal footprint. |
| Feedback Reference | 0.765 V ±1.8% - sets precise output voltage with standard resistor divider; enables outputs as low as 0.8 V. |
| Quiescent Current | 28 µA in ECO mode - extends battery life in always-on sensor nodes and portable instruments. |
| Shutdown Current | 1 µA - ensures near-zero drain during system sleep or storage. |
| Thermal Shutdown | 170°C trip / 160°C recovery - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
SOT-6L (TSOT-6L) package: 2.90 mm × 1.60 mm, low-profile surface-mount, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CB | Bootstrap capacitor connection | Supplies gate drive for internal high-side MOSFET; requires 100 nF ceramic cap between CB and SW. |
| GND | Power and signal ground | Primary return path for VIN, SW, FB, SHDN; must be low-impedance and tied to thermal pad if used. |
| FB | Feedback input | Monitors output via resistor divider; regulates VOUT = 0.765 V × (1 + R1/R2); sensitive to noise-requires local bypass. |
| SHDN | Enable/disable control | High-voltage tolerant (≤60 V); pull ≤1.25 V to disable; internal pull-up allows floating-enable; supports UVLO extension. |
| VIN | Main power input | Supplies internal bias and high-side MOSFET drain; accepts 4–60 V; requires ≥10 µF local ceramic input capacitance. |
| SW | Switch node | Connects to inductor, catch diode (if external), and CB capacitor; carries high dV/dt-must minimize trace area and coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated boot diode | Eliminates external bootstrap diode, reducing BOM count and layout complexity in high-frequency designs. |
| ECO mode with 28 µA IQ | Automatically reduces switching activity at light loads-preserves battery runtime without manual mode control. |
| Overvoltage transient protection (OVTP) | Clamps high-side FET when FB exceeds 108% of 0.765 V, limiting output overshoot during rapid load release. |
| Internal soft-start | Prevents inrush current by ramping COMP node voltage-no external capacitor required for controlled startup. |
| Pulse-by-pulse current limit | Monitors high-side switch current each cycle; limits peak current to 1.2–1.7 A to prevent MOSFET failure under short-circuit. |
Applications
| Industrial Distributed Power | Automotive Body Control |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMR14006YDDAR | 40 V max input, same 600 mA rating and 2.1 MHz frequency; lower RDS(on) (650 mΩ) but no ECO mode (IQ = 45 µA). | Better suited for 12–24 V systems where 60 V tolerance is unnecessary and higher efficiency at medium loads is prioritized. | Select when input voltage never exceeds 40 V and lowest conduction loss-not lowest standby current-is critical. |
| MP2451DT-LF-Z | 36 V max input, 0.6 A, 2 MHz; lacks ECO mode (IQ = 100 µA), no integrated boot diode, and no OVTP. | Lower-cost alternative for non-battery applications where transient suppression and ultra-low IQ are not required. | Choose for cost-sensitive consumer electronics with stable 12–24 V input and moderate efficiency targets. |
Compared with LMR14006YDDAR and MP2451DT-LF-Z, the LMR16006YDDCR uniquely combines 60 V input tolerance, 28 µA ECO mode, integrated boot diode, and OVTP-making it the only option among the three qualified for long-duration battery operation in harsh industrial environments.

FAQ
What is the switching frequency of the LMR16006YDDCR?
The LMR16006YDDCR operates at a fixed 2.1 MHz switching frequency, as designated by the "Y" suffix. This enables compact filter design using small inductors (e.g., 22 µH) and ceramic capacitors while maintaining low output ripple and avoiding interference with common radio bands.
Does the LMR16006YDDCR require an external bootstrap diode?
No-the LMR16006YDDCR integrates the bootstrap diode internally. A 100 nF ceramic capacitor must still be placed between the CB and SW pins to provide gate drive voltage for the high-side MOSFET, but no external diode is needed, simplifying layout and reducing BOM count.
How does ECO mode function in the LMR16006YDDCR?
ECO mode in the LMR16006YDDCR activates automatically when inductor peak current drops below 80 mA and output voltage remains regulated. It disables switching pulses to reduce gate drive and switching losses, lowering quiescent current to 28 µA-ideal for battery-powered standby operation.
What protection features are built into the LMR16006YDDCR?
The LMR16006YDDCR includes pulse-by-pulse overcurrent protection (1.2–1.7 A limit), thermal shutdown at 170°C with 10°C hysteresis, undervoltage lockout (4 V rising threshold), and overvoltage transient protection (OVTP) that disables the high-side FET if FB exceeds 108% of 0.765 V.
Can the LMR16006YDDCR operate with input voltages below 4 V?
No-the LMR16006YDDCR has a specified minimum input voltage of 4 V per its Recommended Operating Conditions. Below this, the internal bias circuitry cannot sustain regulation, and UVLO will hold the device in shutdown. For sub-4 V operation, a different regulator architecture (e.g., LDO or specialized low-VIN buck) is required.
