Frequently Asked Questions
What is the input voltage range of the LM22672MRE-ADJ/NOPB?
The LM22672MRE-ADJ/NOPB accepts an input voltage range from 4.5V to 42V, with a nominal input of 12V. This wide range makes it suitable for 12V and 24V industrial bus systems, automotive applications, and telecom equipment where input voltages can vary significantly.
What is the minimum adjustable output voltage of the LM22672MRE-ADJ/NOPB?
The LM22672MRE-ADJ/NOPB can regulate output voltage as low as 1.285V using an external resistor divider network. This adjustable output capability allows designers to set any voltage between 1.285V and the input voltage, providing flexibility for powering processors, FPGAs, and other logic circuits.
What package does the LM22672MRE-ADJ/NOPB come in?
The LM22672MRE-ADJ/NOPB is available in an 8-pin Small Outline Package (SOIC-8), which offers a compact footprint for PCB designs. The SOIC-8 package provides good thermal performance and is compatible with standard SMT assembly processes, making it easy to integrate into production designs.
What are typical applications for the LM22672MRE-ADJ/NOPB?
The LM22672MRE-ADJ/NOPB is commonly used in industrial power supplies, automotive auxiliary rails, telecommunications equipment, motor drive control boards, and battery-operated instruments. Its 1A output current and wide input range of 4.5V to 42V make it ideal wherever efficient step-down DC-DC conversion from a medium-voltage bus is needed.
How does the adjustable frequency feature benefit the LM22672MRE-ADJ/NOPB design?
The adjustable switching frequency of the LM22672MRE-ADJ/NOPB allows designers to optimize the tradeoff between efficiency, inductor size, and EMI. By selecting an external resistor, the frequency can be tuned to avoid interference with sensitive signal bands, reduce switching losses at lower frequencies, or miniaturize passive components at higher frequencies—enhancing design flexibility.
