The LTC3827IUH#TRPBF is a synchronous monolithic step-down switching regulator, made by Analog Devices. It is designed to deliver a regulated output of up to 18V from a wide input voltage range of 2.5V to 24V. The product features low-profile, thermally enhanced 8-lead TSOT and 8-lead MSOP packages for high efficiency, low noise, and high power capabilities. It internally controls two external N-channel power MOSFETs and features programmable switching frequency and programmable soft-start time for optimized system design. It also has various protection features such as over-current protection, cycle-by-cycle current limit, input under-voltage lockout, and thermal shutdown. Its voltage and current feedback control ensure excellent line and load regulation and fast transient response.
