Frequently Asked Questions
What is the input voltage range of the LM2733YMF/NOPB?
The LM2733YMF/NOPB accepts an input voltage from 2.7V to 14V, making it compatible with single-cell Li-Ion batteries, dual-AA alkaline cells, and regulated 5V or 12V rails. The nominal input voltage is 5V.
What switching frequencies does the LM2733YMF/NOPB support, and how do I select between them?
The LM2733YMF/NOPB supports two switching frequencies: 0.6 MHz and 1.6 MHz. The frequency is selected via a dedicated pin — connecting it to GND selects 0.6 MHz for higher efficiency, while connecting it to VIN selects 1.6 MHz for smaller external passive components and reduced ripple.
What package does the LM2733YMF/NOPB use, and is it RoHS compliant?
The LM2733YMF/NOPB is housed in a 5-pin SOT-23 (SOT23-5) surface-mount package, which is ideal for space-constrained designs. The '/NOPB' suffix confirms it is lead-free and RoHS compliant (Pb-free code: Yes, JESD-609 code: e3).
What is a typical application circuit for the LM2733YMF/NOPB?
A typical boost converter application uses the LM2733YMF/NOPB with an external inductor (1–10 µH), a Schottky diode, an output capacitor, and two resistors to set the output voltage. The integrated 40V FET switch means no external MOSFET is required, keeping the component count minimal and the PCB footprint small.
Where can I buy the LM2733YMF/NOPB and what is the price?
The LM2733YMF/NOPB is available from authorized distributors and component marketplaces worldwide. Pricing starts from approximately $0.48 per unit at volume, with stock available for immediate shipping. Submit a quote request on FindMyChip to get competitive pricing from verified suppliers.
