Applications
The MIC2296BD5 is widely used in white LED backlighting systems for small LCD displays in portable consumer electronics, where a single Li-ion cell must be boosted to 10 V to 34 V for LED string drive. Its high switching frequency of 600 kHz allows use of tiny inductors and ceramic capacitors, reducing total solution size on space-limited PCBs. It also powers USB charging accessories and small industrial instruments requiring boosted rails from low-voltage batteries.

Frequently Asked Questions
What is the maximum output voltage MIC2296BD5 can regulate to and what applications benefit from this range?
The MIC2296BD5 can boost its output voltage up to 34 V from inputs as low as 2.5 V. This range is ideal for driving white LED strings in backlit LCD panels and charging supercapacitors or small Li-ion cells from low-voltage battery supplies in portable equipment.
How does the 600 kHz switching frequency of MIC2296BD5 affect the external component selection?
Operating at 600 kHz allows the use of small-value inductors in the 4.7 µH to 10 µH range and ceramic output capacitors in the 10 µF class, reducing BOM cost and PCB footprint compared to lower-frequency boost converters requiring larger passives.
Can MIC2296BD5 operate directly from a single Li-ion or LiPo battery cell?
Yes. Its input voltage range of 2.5 V to 10 V covers the full discharge range of a single Li-ion cell from 4.2 V charged down to 2.7 V depleted, making it a direct fit for single-cell battery-operated portable devices needing a boosted regulated output.
