The LTC3405AES6#TRMPBF is a high efficiency monolithic synchronous buck regulator from Analog Devices Inc. It operates with a constant frequency current mode architecture, offering up to 96% efficiency.
This regulator is designed for a wide input voltage range of 2.5V to 5.5V, making it suitable for single Li-Ion battery-powered applications. It can supply up to 300mA of output current at a 3V input. The device features a low quiescent current of only 20µA during operation and less than 1µA in shutdown mode, extending battery life.
The switching frequency is internally set at 1.5MHz, allowing for the use of small surface mount inductors and capacitors, contributing to a small PCB footprint. It is stable with ceramic capacitors and supports low output voltages down to 0.8V, thanks to its 0.8V feedback reference voltage. The internal synchronous switch eliminates the need for an external Schottky diode, further enhancing efficiency and simplifying the design.
The LTC3405AES6#TRMPBF is available in a low profile (1mm) ThinSOT-23-6 package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA).
