Frequently Asked Questions
What is the input voltage range of the LM2623MM?
The LM2623MM operates with an input voltage range of 3V to 5V, with a nominal input of 3.3V. This makes it compatible with single-cell Li-ion batteries, USB power rails, and 3.3V system supplies commonly found in portable and IoT devices.
What control method does the LM2623MM use, and why does it matter?
The LM2623MM uses Pulse Frequency Modulation (PFM) voltage-mode control. PFM reduces switching frequency at light loads, significantly lowering quiescent current and improving efficiency in battery-operated applications where standby power is critical.
What package is the LM2623MM available in?
The LM2623MM is available in an SOIC-8 small outline package (JESD-30 code S-PDSO-G8). This compact 8-pin package is well-suited for space-constrained PCB designs in portable consumer electronics and industrial applications.
What are typical applications for the LM2623MM?
Typical applications include battery-powered portable electronics, wearable devices, IoT sensor nodes, USB-powered accessories, and low-power wireless communication modules. The device is ideal wherever a compact, efficient DC-DC boost conversion from a 3V–5V source is required.
Where can I buy the LM2623MM and what is the price?
The LM2623MM is available from global electronic component distributors. Current pricing starts from approximately $0.74 per unit, with worldwide stock and shipping options available through FindMyChip's sourcing network.
