Key Features
- Current-mode PWM control enables both boost and SEPIC topologies from a single 2.7 V to 5.5 V input rail
- Adjustable output voltage from 3 V to 24 V covers a wide range of LED driver and rail generation needs
- Compact 8-pin SOIC package with high switching frequency minimizes external inductor and capacitor size
Applications
The LM2735XMY is used in portable equipment and embedded systems where a single Li-ion or two-cell alkaline supply must generate a regulated output voltage between 3 V and 24 V. Its SEPIC capability makes it valuable for white-LED backlighting, small TFT display bias supplies, and other applications requiring an output that can be above or below the input voltage.

Frequently Asked Questions
What input voltage range does the LM2735XMY accept and what output range can it generate?
The LM2735XMY accepts an input voltage from 2.7 V to 5.5 V, making it compatible with single-cell Li-ion batteries and USB power. Its adjustable output covers 3 V to 24 V, enabling boost conversion to supply white LEDs, RF power amplifiers, or analog circuits from a low-voltage input rail.
What DC-DC topologies does the LM2735XMY support and why is SEPIC useful for battery-powered designs?
The LM2735XMY supports both boost and SEPIC topologies. The SEPIC topology is valuable when the input voltage may be above or below the target output, such as a 3.0 V to 4.2 V Li-ion cell driving a 3.3 V rail—something a simple boost converter cannot handle once the battery voltage exceeds the output.
What control scheme does the LM2735XMY use and how does it affect transient response?
The LM2735XMY uses current-mode PWM control, which provides inherent cycle-by-cycle current limiting and faster transient response than voltage-mode designs. At switching frequencies up to 1.6 MHz, the LM2735XMY allows small external inductors (down to 2.2 µH) and capacitors, reducing total solution size.
Is the LM2735XMY RoHS compliant and what package does it come in?
The LM2735XMY carries a Pb-free code of No, indicating it is not RoHS compliant and uses a leaded package finish. It is housed in an 8-pin SOIC (S-PDSO-G8) package. Engineers targeting lead-free assemblies should verify availability of a compliant variant before designing it into new products.
