LT3942 Synchronous Buck-Boost Converter

Analog Devices Inc. LT3942 Synchronous Buck-Boost Converter is a monolithic 4-switch synchronous buck-boost LED driver. The driver can regulate the LED string current up to 34V with input voltages above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronisable 300kHz to 2MHz fixed-frequency operation, or internal 25% triangle spread-spectrum operation for low EMI. With 3V to 36V input, 0V to 36V output, and seamless low-noise transitions between operation regions, LT3942 is ideal for LED driver applications in automotive, industrial, and battery-powered systems.
