Applications
The MAX1910EUB+T drives white LED backlights in mobile phones, PDAs, and portable instrumentation displays where a 2.7 V to 5.3 V Li-Ion supply must be boosted efficiently to drive series LED strings. Its inductorless switched-capacitor topology reduces EMI and PCB area compared to boost converter solutions, making it ideal for noise-sensitive RF handheld devices. It is also used in keypad backlighting and small LCD panel illumination where compact 10-pin µMAX packaging and low quiescent current extend battery runtime.

Frequently Asked Questions
What input voltage range does MAX1910EUB+T support for single-cell Li-Ion battery-powered LED backlights?
The MAX1910EUB+T accepts input voltages from 2.7 V to 5.3 V, covering the full discharge range of a single-cell Li-Ion battery from 4.2 V (fully charged) down to 2.7 V (depleted). This wide range ensures the LED backlight remains driven at consistent brightness without dropout even as the battery discharges in mobile phones and portable displays.
How do the 1.5x and 2x charge pump modes of MAX1910EUB+T affect LED driver efficiency at different supply voltages?
The MAX1910EUB+T automatically selects the 1.5x charge pump mode when the input is high enough (typically above 3 V) and switches to 2x mode at lower inputs, optimizing conversion efficiency across the 2.7 V to 5.3 V range. Running at 1.5x instead of 2x reduces capacitor switching losses, typically improving efficiency by 5 % to 10 % at 3.3 V input for a 3-LED white backlight string.
Why does the inductorless design of MAX1910EUB+T simplify PCB layout in RF mobile handsets?
The switched-capacitor architecture of MAX1910EUB+T eliminates the inductor required by boost converters, removing the primary source of switching EMI that can interfere with nearby RF circuits operating at 900 MHz or 1800 MHz GSM frequencies. Without an inductor, the PCB layout requires only small fly capacitors and a decoupling capacitor, reducing the 10-pin µMAX footprint's sensitive area to under 10 mm².
What distinguishes the MAX1910EUB+T from a resistor-limited LED drive approach when powering 4 white LEDs from a 3.6 V nominal supply?
A resistor-limited approach wastes voltage headroom as heat, delivering only 60 % to 70 % efficiency for 4 white LEDs from a 3.6 V nominal supply. The MAX1910EUB+T charge pump boosts the supply to provide regulated current to LEDs, achieving over 80 % efficiency and maintaining consistent LED brightness as the 2.7 V to 5.3 V input drops, which a fixed resistor cannot do without visible dimming at low battery.
