Features

Suppressed step-up voltage fluctuations reduces output capacitor noise

PWM brightness control systems often suffer from output capacitor noise problems. ROHM's original technology suppresses output voltage fluctuations, reducing capacitor noise. This eliminates the need for noise countermeasures, decreasing development time.

Applicable models : BD6583MUV-A, BD6592MUV, BD6586MUV, BD6150MUV

  
Expanded
Excellent current accuracy, even with PWM brightness control (BD6583MUV-A, BD6592MUV, BD6586MUV, BD6581GU, BD6150MUV, BD6142MUV)
LED VF fluctuation absorption
93% DC / DC conversion efficiency
Easy line selection (BD6583MUV-A, BD6592MUV, BD6586MUV, BD6150MUV)
