For low input voltages
PREMA ICs PR4401 and PR4402
For batteries (Vcc) up to 1.9 V, standard-ICs PR4401 and PR4402 can be utilized for low ILED and high ILED. Based on the applied Inductor, LED currents ranging from 6.5 mA to 40.0 mA are selectable. Importantly, further external components are not required. Thus, small, light and cost-efficient devices can be fabricated using PR4401 or PR4402.
- supply for white or colored LEDs
- LCD background lighting (e.g. mp3-player, alarm clock)
- supply for operating display
- mini-pocket lamp (e.g. key chain, integrated into car keys)
