Frequently Asked Questions
What is the output voltage and maximum output current of the LM22672MRX-5.0S1?
The LM22672MRX-5.0S1 provides a fixed 5.0V output voltage with up to 1A maximum continuous output current. The fixed output voltage eliminates the need for external resistor dividers, simplifying the PCB layout and reducing component count for standard 5V supply rails.
Does the LM22672MRX-5.0S1 require an external MOSFET?
No, the LM22672MRX-5.0S1 integrates an internal power MOSFET, making it a fully integrated step-down regulator. This simplifies the design by reducing the number of external components required compared to controller-only solutions that need an external FET, gate driver, and associated passive components.
What package does the LM22672MRX-5.0S1 come in and what is its footprint?
The LM22672MRX-5.0S1 is housed in an SO-8 (Small Outline 8-pin) surface-mount package. The compact SO-8 footprint and high switching frequency capability allow designers to use smaller inductors and capacitors, resulting in a very small total solution size suitable for high-density power distribution boards.
What input voltage range does the LM22672MRX-5.0S1 support?
The LM22672MRX-5.0S1 supports a wide input voltage range that accommodates common unregulated DC bus voltages above 5V. This makes it suitable for step-down regulation from standard 12V, 9V, or 7.5V input rails to a regulated 5V output for powering logic, microcontrollers, and communication ICs.
