iW6401

iW6401 Digital Programmable LED Driver IC Company confidential General description iW6401 is a highly versatile digital processor IC for off-line LED drivers in smart lighting applications. With its high degree of configurability it can serve as a platform for a wide range of digital dimming LED applications. Multiple dimming interfaces connect the iW6401 to home or building automation systems: I2C-bus, DLT receiver (IEC 62756 compliant), light switch on/off events using a configurable state machine. Lamp dimming curves are programmable. iW6401 can serve as a power front-end for wireless communication modules, intelligent sensors or generic microcontrollers. An integrated LDO provides a stable supply voltage for external peripherals. All operating parameters and functions are configurable using unique multi-write OTP programming. Digital control loops provide precise control of both input power and light output. A high power factor can be achieved while maintaining stable and flicker...
