The LT3942JUFD#TRPBF is a monolithic 4-switch synchronous buck-boost converter designed for both voltage regulator and LED driver applications. It provides constant voltage and constant current regulation, capable of handling input voltages above, below, or equal to the output voltage.
Key electrical specifications include an input voltage range of 3V to 36V and an output voltage range of 0V to 36V. The device can deliver up to 2A of current and operates at a programmable switching frequency between 300kHz and 2MHz. It supports both analog and PWM dimming with high external dimming ratios.
This LED driver is suitable for automotive and general-purpose lighting applications. It features fault protection for output short-circuit and open or short LED conditions, along with fault reporting. The LT3942JUFD#TRPBF is available in a compact 28-lead QFN (4mm x 5mm) package, designed for surface mounting.
Its AEC-Q100 qualification makes it suitable for demanding automotive environments. The proprietary peak-buck peak-boost current mode control scheme ensures efficient operation and allows for seamless low-noise mode transitions.
