The iW388 high-resolution integrated buck LED driver with Dialog’s True DC dimming technology enables high performance dimmable commercial lighting systems. The device works from a 65V input voltage as a second-stage converter in an AC/DC lighting system or as a stand-alone DC/DC converter. With an integrated 65V power MOSFET, the device offers a simple-to-use IC for applications up to 40W of output power. The iW388 accepts both analog (DC) or PWM dimming inputs to provide an exceptional dimming range from 0.0625% to 100% in 0.0625% steps with an integrated light-off mode. The device also works with a resistor set dimming input to offer a true 3-in-1 dimmer compatibility.
- Single-Stage DC/DC Non-Isolated Buck Regulator with Integrated Power MOSFET
- Supports Wide DC Input Voltage with Tight Output Current Regulation (±3%)
- Output Power up to 40W
- Wide Output Voltage Range Support – 5V to 98% of the Input Voltage
- High Performance Dimming
- 0.0625% Dimming Resolution
- 0.0625% to 100% Dimming Range
- True DC Dimming with No Ripple Across Entire Dimming Range
- Light-Off Mode - Completely Turn-Off LED Light at Minimum Dimming Input
- Two DIM Pins – Supports PWM/Analog Inputs and RSET Input
- RSET + 0-10V
- MCU (DALI or Wireless) + 0-10V
- Supports Constant Current (CC), Constant Voltage (CV), Constant Power (CP) Operating Modes
- Fully Protected
