The LTC3835IDHC-1#TRPBF part from Analog Devices is an 18-V, adjustable, synchronous buck switching regulator. It is designed for DC-DC converter applications that require high efficiency, low-noise, and high-efficiency power conversion. This device features synchronous operation, which eliminates the need for an external Schottky diode, as well as a programmable output current limit and Thermal-Shutdown. Additionally, the LTC3835IDHC-1#TRPBF features an input voltage range from 3.2-V to 18-V, a VOUT range of 0.63 V to 16 V, programmable switching frequency up to 500 kHz, and programmable current mode control. This part is lead-free (RoHS compliant) and is rated for operation across the industrial temperature range of -40°C to +85°C.
