The iW3637 high-voltage, second-stage buck LED driver provides constant current to LEDs directly from DC power supplies. It supports non-isolated buck and flyback converter topologies to post-regulate from a PFC AC/DC boost converter, minimizing low-frequency output ripple current and eliminating virtually all flicker in the system, even down to 1%.
- Single-Stage DC/DC Buck or Flyback Topology
- Supports Wide DC Input Voltage with Tight Output Current Regulation (±3%)
- Output Power up to 150W
- PrimAccurate™ Primary-Side Control for Excellent Output Current Regulation with No Direct Voltage and Current Feedback Components Needed
- Independent Maximum Load Current Setting Interface
- PWM Dimming
- Wide Dimming Range: 1% - 100%, with 1% Resolution
- Configurable Minimum Dimming Setting
- Dim-to-Off, 1%, 5%, or 10%
- Fully Protected
- Output Overvoltage, Output Open, Output Short, Overcurrent, Peak Current Limit, Sense-Resistor Short Protections
- Input Voltage Undervoltage Protection
- Built-In Over-Temperature Protection or External NTC
- Brown-In and Brown-Out Protection
- Small SOIC 8-Lead Package
