MSL2024
Description
The MSL2023/24 LED drivers for two-color systems include a linear current controller for the main string, typically for white LEDs, and a second floating buck controller for a color-adjust LED string. Both the switching and linear controllers drive external MOSFETs to provide flexibility over a wide range of power levels (LED currents and voltages).
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
- Over 100:1 dimming range
