What are the key features of LM2735XSD/NOPB?
- Dual switching frequency (520 kHz or 1.6 MHz) enables flexible trade-off between component size and efficiency
- Wide input range 2.7 V to 5.5 V supports single-cell Li-Ion and regulated 5 V rail designs
- Supports both boost and SEPIC topologies from a single IC, reducing BOM complexity
- Compact SOT-23-6 package saves board space in portable and handheld applications
What is LM2735XSD/NOPB used for?
The LM2735XSD/NOPB is well suited for portable consumer electronics such as smartphones, tablets, and handheld medical devices where a compact, efficient boost converter is needed to step up a battery voltage to a higher regulated output. It also serves industrial sensor modules and white LED driver circuits that require a stable adjustable output voltage from 3 V to 24 V. Its SEPIC capability makes it ideal for automotive and IoT nodes where the input voltage may rise above or fall below the desired output.

Frequently Asked Questions
What is the input voltage range supported by LM2735XSD/NOPB, and how does it affect battery-powered designs?
The LM2735XSD/NOPB accepts input voltages from 2.7 V to 5.5 V, making it compatible with single-cell Li-Ion batteries (nominally 3.7 V) and regulated 5 V rails. This wide 2.7 V lower limit ensures the converter keeps running even as a battery discharges close to its cutoff, extending usable runtime in portable devices without requiring additional circuitry.
How does the choice between 520 kHz and 1.6 MHz switching frequency affect inductor size in LM2735XSD/NOPB designs?
At 1.6 MHz the LM2735XSD/NOPB allows use of inductors as small as 1 µH, significantly shrinking the magnetics footprint compared to the 520 kHz mode which typically requires inductors in the 4.7 µH to 10 µH range. Higher frequency reduces peak inductor current ripple amplitude but increases switching losses, so designers choose 520 kHz when efficiency above 90% is the priority and 1.6 MHz when board area below 10 mm² is the constraint.
When would a designer select the SEPIC topology available in LM2735XSD/NOPB instead of a simple boost converter?
A SEPIC configuration is chosen when the input voltage can swing both above and below the required output voltage, for example in a 2-cell AA battery application where fresh cells provide 3 V but a regulated 3.3 V output is needed throughout the discharge cycle down to 1.8 V. The LM2735XSD/NOPB supports this mode with its adjustable output range of 3 V to 24 V, eliminating the need for a separate buck-boost IC and saving cost in the BOM.
What package does LM2735XSD/NOPB use, and what PCB footprint area does it occupy?
The LM2735XSD/NOPB is housed in a 6-pin small-outline no-lead (SON) package measuring approximately 2 mm × 2 mm, occupying a PCB footprint of roughly 4 mm². This tiny outline is ideal for space-constrained applications such as wearables and compact IoT modules. The device is also RoHS-compliant and lead-free, meeting modern environmental regulations.
