This datasheet provides information on the STLED25, a 5-channel step-up white LED driver with high side current source and PWM dimming. The driver can provide up to 125 mA of total current per channel with a maximum voltage of 7.5 V. It also features a self-test feature to detect any LED failure and disable the related channel.
The STLED25 is a fixed-frequency, high-efficiency boost DC-DC converter featuring five parallel high-side current sources. It is designed to drive up to 125 mA of total LED current with a maximum voltage of 7.5 V per channel, supporting single or dual LED connections. The device includes features such as PWM dimming, automatic shutdown time windows, and a self-test function to detect LED failures.
