What are the key features of LM27313XQMF/NOPB?
- AEC-Q100 automotive qualification enables direct use in ADAS, instrument cluster, and infotainment power-supply designs without additional qualification effort
- 1.6 MHz switching frequency reduces external inductor and capacitor sizes, allowing a complete boost solution in under 20 mm² of board area
- Integrated 30 V power FET in a 5-pin SOT-23 package eliminates external switch components and simplifies PCB layout for space-constrained modules
What is LM27313XQMF/NOPB used for?
The LM27313XQMF/NOPB is well suited for automotive LED lighting supply rails, instrument panel backlights, and ADAS sensor power rails that require a compact boost stage compliant with AEC-Q100. Its 2.7 V to 14 V input range accommodates both 3.3 V and 5 V logic rails stepping up to display or sensor voltages. Industrial handheld devices and portable test equipment also benefit from the high 1.6 MHz switching frequency, which keeps passive component sizes small while maintaining efficient conversion.

Frequently Asked Questions
Why is the LM27313XQMF/NOPB preferred for automotive LED backlight supplies compared to a non-AEC part?
The LM27313XQMF/NOPB carries AEC-Q100 qualification, meaning it has passed automotive-grade stress tests for temperature cycling from -40°C to +125°C, electrostatic discharge, and moisture sensitivity. Using a non-qualified part in an automotive design typically requires a separate qualification campaign that can add 6 months to 18 months to the development timeline, whereas this part can be designed in directly for instrument cluster or infotainment backlight applications.
How does the 1.6 MHz switching frequency of the LM27313XQMF/NOPB help reduce solution size?
At 1.6 MHz, the required inductance for a typical 5 V to 12 V boost stage drops to around 2.2 µH to 4.7 µH, compared to 10 µH to 47 µH needed at 200 kHz to 400 kHz. Smaller inductors have lower DCR and occupy less than 2 mm × 2 mm footprint, enabling the full power supply solution to fit in under 20 mm² on a two-layer PCB alongside the SOT-23-5 IC.
What is the maximum output voltage the internal 30 V FET supports, and when does that limit apply?
The integrated switch is rated to 30 V, which sets the ceiling for the boost output voltage. In practice, designers targeting a 24 V or 28 V rail from a 5 V input can do so safely within this 30 V switch rating. Applications requiring outputs above 28 V should derate by 2 V for margin, and designs targeting 30 V or above would need an external FET solution to avoid stressing the internal switch.
Can the LM27313XQMF/NOPB operate from a single-cell Li-ion battery, and what is the minimum usable voltage?
Yes. The device operates from 2.7 V minimum input, which is below the 3 V cutoff voltage of most single-cell Li-ion batteries, so the converter continues to boost even when the battery is nearly discharged. This makes it practical for wearable devices, portable instruments, and IoT nodes that rely on a 3.7 V nominal Li-ion cell stepping up to a 5 V or 12 V system rail.
