Frequently Asked Questions
What is the input voltage range and maximum output current per channel of the LM26420Q1XSQ/NOPB?
The LM26420Q1XSQ/NOPB accepts an input voltage from 3 V to 5.5 V and delivers up to 2 A per output channel. This makes it practical for automotive 5 V bus systems where two independently regulated rails must power processors, sensors, or communication modules simultaneously.
How does the phase-shift configuration in LM26420Q1XSQ/NOPB benefit the input decoupling capacitor selection?
By interleaving the two switching channels 180 degrees out of phase, the LM26420Q1XSQ/NOPB reduces peak input current draw and input capacitor ripple current by up to 50%. This allows designers to use smaller input capacitors, reducing BOM cost and board area in space-constrained automotive power stages.
For an ADAS sensor module requiring both 1.8 V and 3.3 V rails, how does LM26420Q1XSQ/NOPB simplify the power tree?
The LM26420Q1XSQ/NOPB integrates two independent adjustable buck converters each capable of 2 A, covering both 1.8 V and 3.3 V outputs from a single 5 V supply in one 16-pin QFN package. This eliminates the need for two separate converter ICs, reducing PCB footprint and design complexity.
Is the LM26420Q1XSQ/NOPB suitable for designs that must comply with automotive quality standards?
Yes, the LM26420Q1XSQ/NOPB carries AEC-Q100 automotive qualification, confirming it meets reliability requirements for temperature cycling, humidity, and electrical stress defined by the automotive electronics council. It is rated for operation across automotive-grade temperature ranges, making it appropriate for under-hood and cabin electronics.
