Analog Devices LT3950 is a monolithic 1.5A peak switch current, 60V LED driver. The guaranteed peak switch current rating of the IC is 1.5A, and this is important to know when calculating the maximum output current at a given LED voltage and input voltage for a boost converter. The LT3950 features SSFM and a well-controlled SW node for low emissions. A frequency range of 200kHz to 2MHz and a high-side PWMTG PWM-dimming MOSFET make this a versatile IC for many applications. It can be used for boost, buck-boost mode, and buck mode LED driver applications. The PWMTG MOSFET not only provides high PWM dimming ratio capability but also serves as a short-circuit protection device. The FAULT flag indicates when there is either a short-circuit or open-LED fault at the output.
