Frequently Asked Questions
How many PWM channels does the STLUX325ATR provide, and at what clock frequency do they operate?
The STLUX325ATR provides up to 6 programmable PWM generator channels driven by an on-chip 96 MHz PLL. This combination allows PWM frequency and duty cycle resolution fine enough for flicker-free LED dimming at frequencies above 1 kHz, making it suitable for camera-compatible lighting fixtures and precision power conversion stages requiring tight timing control.
Which lighting protocol does the STLUX325ATR support natively, and what systems does that enable?
The STLUX325ATR natively supports DALI (Digital Addressable Lighting Interface), a standard protocol for addressable digital lighting control in commercial and industrial buildings. DALI integration enables the controller to receive individual dimming commands over a 2-wire bus, allowing up to 64 individually addressed devices per DALI segment without additional protocol translation hardware.
What is the package size of the STLUX325ATR, and how does it affect PCB layout for compact LED driver designs?
The STLUX325ATR uses a VFQFPN-32 (QFN) package measuring 5x5 mm with 1.0 mm height and 32 pins. This compact footprint allows integration of the digital lighting controller into LED driver boards with limited space, such as LED bulb replacements or thin-panel luminaires, where a traditional DIP or SOIC package would occupy 3 to 5 times more board area.
