What are the key features of LM2735XMY/NOPB?
- Dual selectable switching frequency—520 kHz or 1.6 MHz—balances efficiency and component size for layout flexibility
- Supports both boost and SEPIC topologies with adjustable output from 3 V to 24 V for versatile power architectures
- 2.7 V to 5.5 V input voltage range with voltage-mode PWM control enables stable regulation from Li-ion and USB rails
What is LM2735XMY/NOPB used for?
The LM2735XMY/NOPB suits space-constrained portable electronics such as digital cameras, handheld instruments, and wireless sensor nodes that require a regulated output voltage higher than the battery supply. Its SEPIC topology supports applications where the input voltage may be above or below the desired output, making it ideal for single-cell Li-ion powered designs needing a steady 3.3 V or 5 V rail. The 1.6 MHz option allows use of tiny surface-mount inductors and capacitors, reducing total solution footprint on densely packed PCBs.

Frequently Asked Questions
At 1.6 MHz switching frequency, what output inductor size can be used with LM2735XMY/NOPB?
At 1.6 MHz, the LM2735XMY/NOPB allows inductors as small as 2.2 µH to 4.7 µH, compared with 10 µH or larger values needed at 520 kHz. Smaller inductors reduce board height and PCB footprint, enabling ultra-compact power modules in portable cameras and Bluetooth devices. The 8-pin SOT-23 package itself measures under 10 mm², making the full power solution very space-efficient.
Can LM2735XMY/NOPB regulate a 5 V output from a 3.6 V Li-ion battery throughout its full discharge cycle?
Yes. The LM2735XMY/NOPB accepts an input voltage as low as 2.7 V, well below the 3.0 V cutoff of most Li-ion cells, and boosts it to a programmable output up to 24 V. For a 5 V output from a 3.6 V nominal battery, the device operates comfortably within its 2.7 V to 5.5 V input range, maintaining regulation from fully charged at 4.2 V down through end-of-discharge at approximately 3.0 V.
When is a SEPIC topology preferable to a simple boost converter in an LM2735XMY/NOPB design?
A SEPIC topology is preferred when the input voltage overlaps the desired output voltage—for example, powering a 5 V rail from a 4-cell alkaline pack that ranges from 6 V down to 4.0 V. Unlike a boost converter, the SEPIC can regulate the output whether the input is above or below the target, preventing dropout at end-of-life battery voltage. The LM2735XMY/NOPB supports SEPIC operation natively, handling input swings across the full 2.7 V to 5.5 V range with a single chip.
