The LTC3405AES6#TRMPBF is a high-efficiency monolithic synchronous buck regulator from Linear Technology, designed for battery-powered applications. It features a constant frequency, current-mode architecture with a supply current of only 20µA during operation and less than 1µA in shutdown.
With an input voltage range of 2.5V to 5.5V, this regulator is well-suited for single Li-Ion battery applications. It provides 300mA of output current at a 3V input and supports low output voltages down to 0.8V. The switching frequency is internally set at 1.5MHz, allowing for the use of small surface mount inductors and capacitors, and it is stable with ceramic output capacitors.
The device operates with a 100% duty cycle for low dropout operation, extending battery life. The internal synchronous switch eliminates the need for an external Schottky diode, increasing efficiency. The LTC3405AES6#TRMPBF is available in a low profile (1mm) ThinSOT-23-6 package, making it suitable for space-constrained designs.
Key electrical specifications include a high efficiency of up to 96%, ±2% output voltage accuracy, and excellent line and load transient response due to current mode operation. It also includes overtemperature protection.
