Frequently Asked Questions
What is the input voltage range of the LM22675MRE-5.0/NOPB/BKN?
The LM22675MRE-5.0/NOPB/BKN supports an input voltage range of 4.5V to 42V, making it suitable for a wide variety of power supply rails found in automotive, industrial, and telecommunications applications.
What output voltage does the LM22675MRE-5.0/NOPB/BKN provide, and can it be adjusted?
This device is factory-configured for a fixed 5.0V output voltage. It is not adjustable through external resistors like the adjustable version (LM22675); the fixed output simplifies the design by eliminating the external feedback resistor network.
What is the maximum output current of the LM22675MRE-5.0/NOPB/BKN?
The LM22675MRE-5.0/NOPB/BKN can deliver up to 1A of continuous output current. It integrates an internal power switch, reducing the number of external components required and simplifying PCB layout.
How does the precision enable feature work on the LM22675MRE-5.0/NOPB/BKN?
The precision enable pin allows the user to set an accurate UVLO (undervoltage lockout) threshold using an external resistor divider. This ensures the converter starts and shuts down at well-defined input voltage levels, which is especially useful in battery-powered or automotive systems where supply voltage can vary significantly.
What switching frequency does the LM22675MRE-5.0/NOPB/BKN operate at, and can it be changed?
The LM22675MRE-5.0/NOPB/BKN has an adjustable switching frequency set via an external resistor connected to the RT pin. The frequency can be programmed over a range of approximately 50kHz to 1MHz, allowing designers to optimize the trade-off between efficiency, inductor size, and EMI performance.
