Small LED Driver IC

Although Switch-mode and PWM or Pulse Width Modulation methods make very efficient drivers for LEDs, they are also a good source of electromagnetic noise. Many applications require low noise conditions for proper operations, especially those related to medical. These low-noise applications benefit from linear circuits that introduce far lower noise in the system as compared to the Switch-mode or PWM topologies. For driving LEDs linearly, Infineon Technologies AG offers a small LED driver IC, Read more [...]
