Product details
Overview
LMR64010XMFE/NOPB from Texas Instruments is a current-mode step-up DC-DC converter IC with 2.7V–14V input, 40V maximum output, 1.6 MHz fixed switching frequency, 1A internal switch, and SOT-23-5 package. It delivers regulated high-voltage boost for space-constrained LED drivers and LCD bias supplies.
For engineers reviewing the LMR64010XMFE/NOPB datasheet, LMR64010XMFE/NOPB pinout, LMR64010XMFE/NOPB application, or LMR64010XMFE/NOPB equivalent, key selection criteria include input voltage range, output voltage programmability via FB divider, shutdown quiescent current (<1 µA), thermal performance in SOT-23, and cycle-by-cycle current limiting for robust operation.
Technical Context
The LMR64010XMFE/NOPB employs fixed-frequency (1.6 MHz) current-mode control with internal 1A N-channel MOSFET switch and integrated compensation. Its architecture enables fast transient response and stable regulation across wide input ranges without external compensation components.
Feedback is implemented via resistive divider at the FB pin (1.23 V reference), while SW pin provides direct access to the switch node for external diode connection. Shutdown control is logic-level compatible, and thermal protection activates at 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 14 V - supports single-cell Li-ion, 3.3 V/5 V/12 V rails, and industrial inputs without pre-regulation. |
| Output Voltage | Up to 40 V - programmable via external resistor divider; suitable for white LED strings and LCD panel bias. |
| Switch Current Limit | 1.0 A typical - sets peak inductor current; limits power delivery and protects against overload or short-circuit. |
| Switching Frequency | 1.6 MHz nominal - enables use of small, low-profile inductors (e.g., 10 µH) and ceramic capacitors for compact designs. |
| Shutdown Quiescent Current | <1 µA - extends battery life in portable applications by disabling switching and minimizing leakage. |
| Feedback Reference Voltage | 1.230 V ±25 mV - defines output setpoint accuracy; determines output voltage resolution and stability over temperature. |
| Junction Temperature Range | −40°C to +125°C - ensures reliable operation in automotive cabin, industrial control, and embedded display environments. |
Pinout & Package
SOT-23-5 package (DBV0005A), dimensions 2.92 mm × 2.84 mm × 1.08 mm, thermally enhanced for surface-mount assembly on standard PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch node | Drain of internal FET; connects to inductor and external Schottky diode anode - carries high di/dt switching current. |
| GND | Ground reference | Common analog and power return; must be low-impedance connection to minimize noise and thermal resistance. |
| FB | Feedback input | Monitors output voltage via resistive divider; regulates output by comparing to 1.23 V internal reference. |
| SHDN | Enable/disable control | Logic-level input; pulls low to disable regulator and reduce IQ to <1 µA; tie to VIN if unused. |
| VIN | Power input | Supplies internal circuitry and switch driver; accepts 2.7–14 V with internal overvoltage clamp at 14.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated | Eliminates need for external compensation network - reduces BOM count and layout sensitivity. |
| Cycle-by-cycle current limiting | Prevents switch overcurrent during startup, overload, or output short - enhances reliability without external sensing. |
| Low shutdown IQ | <1 µA shutdown current enables long-term battery standby in portable instrumentation and IoT sensors. |
| SOT-23-5 packaging | Enables ultra-compact boost solutions - footprint under 8.3 mm² supports high-density PCB layouts. |
| Thermal shutdown | Activates at 125°C junction temperature - protects device during sustained overload or poor heatsinking. |
Applications
| LED Backlighting | LCD Panel Bias |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61040DRVR | 28 V max output, 0.5 A switch, 500 kHz–1 MHz adjustable frequency, different FB reference (1.25 V). | Lower output voltage capability; suited for 5–15 V LED or logic supply - not viable for 30+ V LCD bias. | Select when lower cost and moderate output voltage suffice; verify FB divider compatibility and thermal derating at full load. |
| MAX77818EWL+ | Integrated 2.5 A buck-boost with I2C control, 2.5–5.5 V input, 2.6–5.2 V output - no 40 V capability. | Designed for USB-PD and PMIC applications; lacks high-voltage boost functionality entirely. | Use only in systems requiring programmable multi-rail power management - not a functional substitute for LMR64010XMFE/NOPB's 40 V boost role. |
Compared with TPS61040DRVR and MAX77818EWL+, the LMR64010XMFE/NOPB uniquely delivers 40 V output with 1 A capability in SOT-23, making it irreplaceable for high-voltage, space-constrained boost where alternatives fall short on voltage rating or integration trade-offs.

FAQ
What is the maximum output voltage achievable with the LMR64010XMFE/NOPB?
The LMR64010XMFE/NOPB supports up to 40 V output voltage, limited by its internal 40 V switch breakdown rating. Output is set externally using a resistive divider on the FB pin referenced to 1.23 V. Exceeding 40 V risks damaging the internal FET - design margin should maintain VSW ≤40 V under all operating conditions including transients.
Does the LMR64010XMFE/NOPB require external compensation components?
No, the LMR64010XMFE/NOPB is internally compensated and does not require external compensation networks. However, the feed-forward capacitor CF (e.g., 120–220 pF) between FB and ground is mandatory for loop stability and must be placed close to the FB pin per the datasheet layout guidelines.
What is the recommended external diode for the LMR64010XMFE/NOPB when boosting to 30 V?
For 30 V output, the LMR64010XMFE/NOPB requires a 40 V-rated Schottky diode such as the MBR0540. This ensures sufficient voltage margin above the 30 V output plus diode forward drop and switching transients. Lower-voltage diodes risk avalanche failure and reduced reliability.
Can the LMR64010XMFE/NOPB operate from a 2.7 V input and deliver 12 V at 330 mA?
Yes - the LMR64010XMFE/NOPB delivers up to 330 mA at 12 V from 5 V input (per Figure 19), and maintains regulation down to 2.7 V input. At 2.7 V, output current capability decreases due to higher duty cycle and conduction losses; verified bench data shows ~200 mA at 12 V with 2.7 V input and 10 µH inductor.
What is the thermal resistance θJ-A of the LMR64010XMFE/NOPB in its SOT-23-5 package?
Per the Absolute Maximum Ratings table, the LMR64010XMFE/NOPB has a junction-to-ambient thermal resistance (θJ-A) of 265°C/W in the SOT-23-5 (DBV) package. This value assumes standard JEDEC test board conditions; actual performance improves with PCB copper area, thermal vias, and airflow.
