Frequently Asked Questions
What is the input voltage range and output current of the LM22679QTJE-5.0/NOPB?
The LM22679QTJE-5.0/NOPB accepts input voltages from 4.5V to 42V with a nominal 12V input, and delivers a fixed 5V output at up to 5A. This wide input range makes it ideal for 12V and 24V automotive battery systems as well as 36V industrial power rails.
Is the LM22679QTJE-5.0/NOPB suitable for automotive applications?
Yes, the LM22679QTJE-5.0/NOPB carries the AEC-Q100 automotive qualification (indicated by the Q suffix), meeting the stringent reliability and test standards required for automotive electronics. It is appropriate for use in body control units, ADAS modules, infotainment systems, and other in-vehicle power supply applications.
What control modes does the LM22679QTJE-5.0/NOPB support?
The LM22679QTJE-5.0/NOPB operates primarily in voltage-mode PWM (Pulse Width Modulation) control and also supports PFM (Pulse Frequency Modulation) for improved light-load efficiency. This combination allows the regulator to maintain high conversion efficiency across the full load range from nearly zero to 5A.
What protection features does the LM22679QTJE-5.0/NOPB include?
The LM22679QTJE-5.0/NOPB features adjustable soft-start to limit inrush current during power-up, programmable current limiting to protect against overload conditions, and is housed in a 7-pin eSOP package providing thermal pad cooling. These protections ensure reliable operation in demanding automotive and industrial environments.
