ROHM's multi-lamp LED drivers make it easier than ever before to incorporate white LEDs in existing illumination applications. Original technology eliminates brightness differences, even with parallel configurations, while PWM control enables flexible brightness adjustment.
Features
A wide input voltage range, from 3.1V to 22V, ensures compatibility with lithium ion batteries (1-4 cells) as well as AC power.
93% conversion efficiency has been achieved through optimization of circuit current and technical expertise, prolonging battery life and simplifying thermal design.
A maximum voltage difference of 2.6V between pins can be absorbed, eliminating brightness differences due to varying VF.
The PWM brightness control method enables the current to be maintained up to a 1% duty cycle. (BD6583MUV)
Original technology is used to mitigate step-up circuit output voltage fluctuations, severely limiting capacitor noise. (BD6583MUV)
Brightness differences are particularly noticeable during low light conditions. However, PWM control features a current tolerance between lines of ±3%, eliminating brightness fluctuations under any condition. (BD6583MUV)
