Frequently Asked Questions
What switching frequency does the LM3224MM-ADJ operate at?
The LM3224MM-ADJ operates at a fixed 1.6 MHz switching frequency. This high frequency allows designers to use smaller external inductors and capacitors, reducing overall PCB footprint in space-constrained portable designs.
Why choose the MSOP-8 package variant of the LM3224MM?
The LM3224MM-ADJ uses an 8-pin MSOP package, which provides a compact and space-efficient footprint compared to larger SOIC alternatives. This makes it well-suited for portable and wearable devices where board area is constrained.
Which application circuits benefit most from the LM3224MM-ADJ boost topology?
The LM3224MM-ADJ is ideal for LED driver circuits, LCD bias generation, and wireless sensor node power supplies. Its adjustable output and 1A switch current make it well-suited for single-cell Li-ion battery boosting in handheld consumer electronics.
How does the LM3224MM-ADJ compare to the TPS61023 in boost converter designs?
Both the LM3224MM-ADJ and TPS61023 are adjustable-output boost converters from Texas Instruments, but they differ in package and switch current rating. The LM3224MM-ADJ uses an MSOP-8 package with 1A peak current, while the TPS61023 targets higher-efficiency designs in a smaller SOT-23 footprint.
Does the LM3224MM-ADJ meet RoHS and lead-free requirements?
Yes, the LM3224MM-ADJ is fully RoHS compliant and manufactured as a lead-free (Pb-free) component. It meets EU RoHS Directive restrictions on hazardous substances, making it suitable for global commercial and industrial product certifications.
