Frequently Asked Questions
What is the input voltage range of the LM2623AMM/NOPB?
The LM2623AMM/NOPB supports an input voltage range from 0.8V minimum to 14V maximum, with a nominal operating voltage of 3.3V. This wide range makes it suitable for single-cell Li-ion batteries, alkaline cells at end-of-life, and regulated 3.3V or 5V supply rails in boost converter designs.
What control method does the LM2623AMM/NOPB use, and why does it matter?
The LM2623AMM/NOPB uses voltage-mode control with Pulse Frequency Modulation (PFM). PFM reduces switching losses at light loads by varying switching frequency instead of duty cycle, resulting in higher power efficiency in battery-powered applications such as IoT sensors, wearables, and portable instruments.
What package does the LM2623AMM/NOPB come in, and is it RoHS compliant?
The LM2623AMM/NOPB is available in an 8-pin Small Outline IC (SOIC) package, JEDEC code S-PDSO-G8. It is fully Pb-free and RoHS compliant per JESD-609 code e3, making it suitable for environmentally regulated consumer, industrial, and automotive applications.
What are typical applications for the LM2623AMM/NOPB?
Typical applications include boost converters for single-cell battery-powered devices, portable handheld equipment, wireless sensor nodes, IoT edge devices, and low-voltage power rails in industrial control systems. Its 0.8V minimum input voltage is especially useful for extending usable battery life in end-of-discharge scenarios.
