Frequently Asked Questions

What is the maximum output voltage LMR62421XSD/NOPB can deliver in adjustable mode?

In adjustable mode, LMR62421XSD/NOPB can regulate output voltages up to 24 V from an input supply as low as 2.7 V. This wide output range makes it suitable for generating bias voltages for op-amps, ADCs, and LCD panels in battery-powered systems.

How much output current can LMR62421XSD/NOPB provide, and what control scheme does it use?

LMR62421XSD/NOPB provides up to 2.1 A peak switch current using current-mode PWM control. Current-mode control simplifies loop compensation, improves line transient response, and allows cycle-by-cycle current limiting, making it robust for applications drawing continuous load from portable 5 V rails.

Which battery chemistries are compatible with the LMR62421XSD/NOPB input voltage range?

The 2.7 V to 5.5 V input range accommodates single-cell lithium-ion batteries (nominally 3.6 V to 4.2 V), two-cell alkaline stacks (nominally 3 V), and USB 5 V rails. This flexibility suits designs that must continue operating as the battery discharges below 3 V.
