Product details
Overview
LMR62014XMF/NOPB from Texas Instruments is a current-mode, fixed-frequency (1.6 MHz) step-up DC-DC switching regulator in a 5-pin SOT-23 package, delivering up to 20V output from 2.7V–14V input with 1.4A internal switch current limit and >90% duty cycle capability. It enables compact boost solutions for space-constrained portable electronics requiring stable high-voltage rail generation.
For engineers reviewing the LMR62014XMF/NOPB datasheet, LMR62014XMF/NOPB pinout, LMR62014XMF/NOPB application, or LMR62014XMF/NOPB equivalent, key selection criteria include input voltage range (2.7V–14V), output voltage programmability via FB divider, thermal performance in SOT-23 (θJ-A = 265°C/W), and shutdown quiescent current (<1 µA).
Technical Context
The LMR62014XMF/NOPB uses peak-current-mode control with an internal 1.4A N-channel MOSFET switch and integrated ramp generator, enabling fast transient response and inherent cycle-by-cycle overcurrent protection. Its fixed 1.6 MHz switching frequency allows use of small external magnetics and ceramic capacitors.
Feedback regulation is achieved via a precision 1.23V reference at the FB pin, with line regulation of ±0.02%/V and temperature drift <±10 mV over −40°C to +125°C. Internal compensation eliminates need for external compensation components beyond feed-forward capacitor CF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 14V - supports single-cell Li-ion, 3.3V/5V/12V rails without pre-regulation. |
| Output Voltage Range | Up to 20V - programmable via external resistor divider; minimum regulated output ≥5.4V at 2.7V input. |
| Switch Current Limit | 1.4A typical - sets maximum deliverable load current under continuous conduction mode. |
| Switching Frequency | 1.6 MHz ±15% - enables <10 µH inductors and low-ESR ceramic capacitors for minimal board area. |
| Feedback Reference Voltage | 1.230 V ±25 mV - defines output setpoint accuracy; used with R1/R2 to scale VOUT = 1.23 × (1 + R1/R2). |
| Shutdown Quiescent Current | <1 µA - extends battery life in always-on systems by disabling switching and bias circuits. |
| Max Duty Cycle | 93% - enables high boost ratios (e.g., 3.3V → 12V or 5V → 18V) in continuous conduction mode. |
Pinout & Package
LMR62014XMF/NOPB is housed in a 5-pin SOT-23 (DBV) package measuring 2.92 mm × 2.84 mm × 1.08 mm, with exposed pad not electrically connected. Thermal resistance θJ-A = 265°C/W enables operation up to +125°C junction temperature with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Drain of internal N-FET switch | Connects to inductor and Schottky diode anode; carries pulsed high-current switching node. |
| GND | Analog and power ground | Common return for feedback, control logic, and switch current path; requires low-impedance PCB connection. |
| FB | Feedback input | Senses output voltage via resistive divider; regulates output by maintaining 1.23V at this pin. |
| SHDN | Logic-level shutdown control | Pull low to disable regulator; tie to VIN if unused; input threshold: 0.5V (OFF), 1.5V (ON). |
| VIN | Power input | Supplies internal bias and switch driver; accepts 2.7V–14V with <1 µA shutdown leakage. |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated control loop | Eliminates external compensation network; only feed-forward capacitor CF required for stability. |
| Cycle-by-cycle current limiting | Prevents switch overcurrent during startup, short-circuit, or overload without external sensing. |
| Thermal shutdown protection | Automatically disables switching if junction temperature exceeds safe limit; recovers when cooled. |
| Low EMI layout support | Fixed-frequency operation and minimized high-di/dt loop area enable robust noise performance in dense layouts. |
| WEBENCH® Power Designer enabled | Full simulation, BOM generation, and thermal analysis available directly from TI's online design tool. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61040DRVR | Lower max output (28V), 0.5A switch, 1.2 MHz switching, smaller 6-pin SOT-23 package. | Better suited for ultra-low-power (<100 mA) applications; lacks 1.4A capability for high-current LED or RF loads. | Select TPS61040DRVR when size and quiescent current (20 µA active) outweigh current capability needs. |
| MAX77818EWL+ | Integrated dual-phase boost with I2C control, 3A total output, QFN-20 package, higher cost and complexity. | Targets multi-rail PMIC designs requiring programmable sequencing and telemetry, not discrete boost. | Choose MAX77818EWL+ only when system-level integration, diagnostics, or multiple regulated outputs are required. |
Compared with TPS61040DRVR and MAX77818EWL+, the LMR62014XMF/NOPB delivers optimal balance of 1.4A current capability, 1.6 MHz frequency, and SOT-23 footprint for cost-sensitive, medium-power boost applications-without sacrificing thermal robustness or design simplicity.

FAQ
What is the maximum output voltage achievable with LMR62014XMF/NOPB?
The LMR62014XMF/NOPB supports output voltages up to 20V, as confirmed in its official datasheet (SNVS735B). This limit arises from internal switch voltage rating (SW pin max = +22V) and practical stability constraints. Output voltage is set externally via the FB resistive divider, and operation above 20V risks exceeding absolute maximum ratings and degrading reliability.
Can LMR62014XMF/NOPB operate from a 2.5V input source?
No - the LMR62014XMF/NOPB has a specified minimum input voltage of 2.7V per its Absolute Maximum Ratings and Electrical Characteristics tables. At 2.5V, the internal bias circuitry fails to activate, resulting in no switching action or regulation. For sub-2.7V inputs, consider TI's TPS61200 or similar ultra-low-VIN boost regulators.
What is the recommended inductor value for LMR62014XMF/NOPB in a 5V-to-12V boost application?
Texas Instruments recommends a 10 µH inductor for 5V-to-12V boost operation with the LMR62014XMF/NOPB, as validated in Figure 19 (Basic Application Circuit) and Figure 20 (Inductor Current waveform) of SNVS735B. This value balances ripple current, efficiency (>90%), and continuous conduction mode across typical loads up to 500 mA.
Does LMR62014XMF/NOPB require an external compensation network?
No - the LMR62014XMF/NOPB features internal compensation, eliminating the need for external Type-II or Type-III compensation networks. Only a feed-forward capacitor (CF = 220–330 pF) between FB and GND is required to ensure loop stability, as specified in the Application Hints section of SNVS735B.
Is LMR62014XMF/NOPB RoHS compliant and lead-free?
Yes - the LMR62014XMF/NOPB is RoHS compliant and lead-free, as confirmed in TI's PACKAGE OPTION ADDENDUM (11-Nov-2025), where "RoHS" is marked "Yes" and "Lead finish/Ball material" is listed as "SN" (tin). The device meets JEDEC J-STD-020 moisture sensitivity Level-1 and is qualified for reflow up to 260°C.
