Product Overview: LT3686EDD#TRPBF

The LT3686EDD#TRPBF is a high-performance, adjustable frequency, 2A step-down switching regulator from Linear Technology. It is designed to maintain a compact footprint while delivering efficient power conversion with robust features suitable for a wide range of applications.

Key Features

• High Efficiency: The LT3686EDD#TRPBF can convert input voltages from 3.6V to 36V down to a range of output voltages, making it versatile for various applications. Its high efficiency minimizes the need for heat sinking and allows for a more compact overall design.
• Adjustable Switching Frequency: With an adjustable switching frequency from 300kHz to 2.2MHz, designers can optimize the regulator for size, efficiency, and component cost. The higher frequency capability allows the use of smaller, lower-cost inductors and capacitors to minimize the size of the power supply.
• Burst Mode® Operation: The LT3686EDD#TRPBF features Burst Mode operation, which reduces quiescent current to just 85μA during light loads or standby, significantly improving battery life in portable applications.
• Integrated Features: It includes a 0.8V feedback reference voltage, a catch diode, a boost diode, and a frequency foldback feature, which helps prevent inductor current runaway during startup and transient conditions.
• Thermal Performance: The device is housed in a 10-lead (3mm x 3mm) DFN package with a thermal resistance that allows for full 2A outputs in high ambient temperatures without the need for airflow or additional heat sinking.
• Protection Features: The LT3686EDD#TRPBF provides several protection features including overvoltage protection, overcurrent protection, and thermal shutdown to ensure reliable operation under fault conditions.
