Resources for iW350
Description
The iW350 is a secondary-side PWM signal generator that works with three types of dimming inputs: PWM dimming, 0V to 10V linear dimming, or simple dimming using a single resistor to ground from the DIM pin. With its extensive configurability, the iW350 offers programmable maximum dimming voltage, minimum duty cycle, turn-off function, and PWM output frequency range, making the device highly flexible for dimmable commercial SSL lighting applications.
The iW350 converts any of the compatible dimming signals into a 1% to 100% PWM duty cycle output that provides a dimming signal to a primary-side LED driver such as the iW3636, eliminating the need for transformers or other driver circuitry.
