Application Scenarios & Design Considerations

Accurate non-dimmable LED driver IC

Alternative Part Number

  • AL8860WT --: Buck LED driver with integrated switch in SOT-23-6, similar input voltage range and current capability, pin-compatible footprint for many SSL21101T designs.
  • PT4115 --: Widely used buck LED driver in SOT-89/SOT-23-5 with comparable current rating and simple external component count, suitable drop-in replacement for low-power LED strings.
  • HV9910B --: Constant-current LED driver controller with wide input voltage range and PWM dimming, functionally similar to SSL21101T for offline and DC LED lighting applications.
