The LTC3547EDDB-1#TRMPBF is a synchronous step-down DC-DC converter and low-noise LDO linear regulator, produced by Analog Devices. The device is capable of supplying up to 2 A of continuous output current, with a parts per million (ppm) line and load regulation for LED backlighting, RF power amplifiers, cameras, and automotive displays. It features an input voltage range between 2.7 V and 5.5 V, an adjustable output voltage from 0.8 V to 5 V, and an adjustable switching frequency from 500 kHz to 1.2 MHz. The device also provides adjustable soft-start, and over current and short-circuit protection. Additionally, it provides low RONsleep mode, and low quiescent current in the LDO mode. The device is available in a 14-lead, 4 × 4 mm body, Pb-free package and is rated for operation temperatures between -40°C and +125°C.
