The LTC3726IGNTR is an integrated synchronous buck controller with power tracking from Analog Devices, Inc. It is a high performance, integrated, fixed frequency, synchronous step-down DC/DC controller featuring all-internal, adaptive loop regulation, accurate input, output and power tracking, and primary side current sense for simplified design and lowest system cost. The device also features integrated high-side and low-side drivers, maximum duty cycle tracking with separate tracking thresholds and current compensation, and internal soft-start. The synchronous rectifier design eliminates the need for a Schottky diode and also reduces conduction losses. The LTC3726IGNTR has protection features such as current limit, power limit, overtemperature shutdown and undervoltage lockout.
