MSL2023 - 2-String LED Driver

General Description

1.

3.

Key Features

  • Dual-string LED driver for 2-color or 2 unequal VF LEDs.
  • Phase shifted register controlled dimming (MSL2023).
  • Individual PWM inputs (MSL2024).
  • Adaptively controls headroom of AC/DC or DC/DC, isolated or non-isolated topologies.
  • Main LED string driven by linear current controller.
  • Drives external N-channel MOSFET.
  • ± 3% current accuracy, no ripple current.
  • 8-bit DAC for peak current control.
  • Color-adjust LED string uses floating buck controller.
  • D.
