Typical Applications
LMR64010XMFX/NOPB-Q1 is suitable for 6 applications: Automotive LCD Display Bias, White LED Backlight Driver, Op-Amp and Sensor High-Voltage Rails, Battery-Powered Portable Devices, Industrial PLC and Sensor Hubs, Automotive ADAS Module Auxiliary Rails.
Automotive LCD Display Bias
The LMR64010XMFX/NOPB-Q1 boosts a 5V or 12V automotive rail to the 16V-40V levels needed for LCD display bias and VCOM drivers, and its AEC-Q100 (-Q1) qualification directly addresses automotive reliability requirements. The 1.6 MHz fixed switching keeps ripple components away from the display driver bandwidth, and the internal 1A switch eliminates external FETs, shrinking the solution to a SOT-23 footprint with a small 10uH-class inductor.
Recommended
White LED Backlight Driver
For LED backlight strings requiring 20V-40V drive headroom from a 5V input, the LMR64010's 40V switch rating and adjustable feedback enable constant-voltage bias with current-setting resistors or an external current sense. The 1.6 MHz frequency permits small 2mm-class inductors and ceramic output capacitors, key for thin automotive and industrial display modules, while cycle-by-cycle current limit protects against shorted LED strings.
Recommended
Op-Amp and Sensor High-Voltage Rails
Precision analog front ends often need 15V-30V rails from a single 5V supply. The LMR64010 generates these rails with a current-mode loop that responds quickly to load transients from switched sensor channels. Following it with a low-noise LDO removes switching ripple for the analog rail, combining boost efficiency with LDO noise performance - a common two-stage architecture in test and measurement and medical sensing boards.
Recommended
Battery-Powered Portable Devices
With a 2.7V minimum input, the LMR64010 operates directly from single-cell Li-ion and even two-cell alkaline packs, boosting to the 12V-30V levels needed by pyroelectric IR sensors, vacuum fluorescent displays, or piezo actuators. The internal 1A switch and SOT-23 package keep height and area minimal for handheld enclosures, and thermal shutdown protects against blocked-vent faults in compact products.
Recommended
Industrial PLC and Sensor Hubs
Industrial 24V-system boards commonly derive a lower internal rail and then boost locally for analog outputs, HART modems, or sensor excitation needing 20V-36V. The 14V input ceiling supports post-buck 12V buses, and the fixed 1.6 MHz clock avoids interference with 4-20 mA and low-frequency industrial signaling. The standard LMR64010XMFX/NOPB suits industrial-grade deployments, with -Q1 for extended-reliability segments.
Recommended
Automotive ADAS Module Auxiliary Rails
Camera and radar modules in ADAS platforms need auxiliary 20V-40V rails for bias networks, heater elements, or photodiode reverse bias. The -Q1 qualified LMR64010 provides these from a 5V or 8V module rail within an AEC-Q100 bill of materials. Its 1.6 MHz operation stays clear of radar IF bands, and the tiny SOT-23 solution fits dense module PCBs where inductor size dominates board area.

Key Differentiators
- AEC-Q100 automotive qualification (vs LMR64010XMFX/NOPB)
- 40V internal switch in SOT-23 (vs LM2731XMFX/NOPB)
- Newer SIMPLE SWITCHER platform vs legacy (vs LM2733XMFX/NOPB)
Design Notes
Keep the SW-GND-diode loop as short as possible: place the inductor, catch diode, and input capacitor within 2-3 mm of the SOT-23 pins. The 1.6 MHz switching edges generate high di/dt; a compact loop minimizes radiated EMI and ring on the switch node. Use a solid ground plane under the part and a 10uF ceramic input capacitor with X7R dielectric to prevent input dips during switch on-time.
Select a catch diode rated at least 40V reverse and rated for the full average output current - a Schottky such as a 40V/1A type minimizes loss. Budget inductor saturation current above the 1A switch current limit. Remember that in a boost converter, average input current exceeds output current; at 5V-to-24V conversion, 100 mA output draws roughly 500 mA from the input.
The SOT-23 package has limited dissipation; losses come from switch conduction, diode, and inductor DCR. At high boost ratios or outputs above ~100 mA, estimate efficiency from the datasheet curves and verify junction temperature stays within the -Q1 grade limit. Adding 2 oz copper and thermal vias under GND reduces theta_JA meaningfully in this footprint.
