Frequently Asked Questions
What input voltage range does the LTC3526BEDC#TRMPBF support, and what output voltages can it regulate to?
The LTC3526B accepts an input voltage from 1 V to 4.5 V and can regulate the output anywhere from 1.6 V to 5.25 V in adjustable mode. This covers single-cell Li-Ion batteries down to end-of-life as well as two-cell alkaline configurations, giving designers flexible power-rail options.
How much output current can the LTC3526BEDC#TRMPBF deliver, and is it suitable for powering a microcontroller plus wireless transceiver simultaneously?
The converter delivers up to 500 mA of output current at its 1 MHz switching frequency, which is sufficient to supply a low-power microcontroller drawing roughly 50 mA alongside a wireless transceiver that peaks at 200 mA to 300 mA during transmission bursts.
Why does the 2 mm × 2 mm DFN package make the LTC3526B a preferred choice for space-constrained wearable designs?
The 6-pin DFN package occupies only 4 mm² of board area, far smaller than SOIC-8 alternatives. Combined with its 1 MHz operation that allows small external inductors of around 2.2 µH to 4.7 µH, the total solution footprint is compact enough for smartwatches or medical patches where every square millimeter counts.
