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 in
Renesas provides a recommended PCB layout guide in their application note (APN) document, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The IW350-02B has a built-in overcurrent protection feature, but it's recommended to add an external overcurrent protection circuit to ensure reliable operation. Renesas provides a reference design for overcurrent protection in their application note (APN) document.
While the datasheet specifies the recommended input voltage range, the maximum allowed voltage deviation is typically ±10% of the nominal input voltage. However, it's recommended to consult with Renesas support or refer to the application note (APN) document for specific guidance.
Renesas provides EMC guidelines and recommendations in their application note (APN) document, including layout considerations, filtering, and shielding techniques to ensure EMC compliance.
Renesas provides a recommended soldering profile in their packaging and assembly document, which includes guidelines for temperature, time, and peak temperature to ensure reliable soldering.
