LTC3405AES6

The LTC3405AES6 is a high-efficiency, step-up DC/DC converter designed by Linear Technology (now part of Analog Devices). It is particularly suited for low-voltage battery-operated devices due to its ability to boost input voltages from as low as 0.5V to a stable output voltage. The LTC3405AES6 operates at a fixed frequency of 1.2MHz, which allows the use of tiny surface-mount inductors and capacitors, essential for compact applications.
One of its key features is its low quiescent current, which maximizes battery life. It achieves an efficiency of up to 94% and can deliver output currents of up to 300mA. The device also includes an anti-ringing control that reduces EMI, soft-start to limit inrush current, and over-temperature protection to enhance reliability.
The LTC3405AES6 is available in a small SOT-23 package, making it ideal for space-constrained designs. It is commonly used in applications like portable electronics, wireless sensors, and other battery-powered devices where efficient power conversion and small form factors are critical.

The LTC3405AES6 is a high-efficiency, monolithic, synchronous step-down DC/DC converter optimized for portable electronics. Operating from a 2.5V to 5.5V input range, it can deliver up to 300mA of continuous output current. Notable features include a low quiescent current of 20µA, ensuring efficiency at light loads, and a shutdown current of less than 1µA. The device operates at a fixed 1.5MHz frequency, allowing the use of small inductors and capacitors, which minimizes the solution footprint.
The LTC3405AES6 incorporates a current mode architecture that offers fast transient response and ease of loop stabilization. It also includes a low dropout 100% duty cycle operation, enabling the output voltage to come very close to the input voltage. Other features include an internal soft-start to limit inrush current, over-temperature protection, and short-circuit protection for reliability. It is available in a compact 6-lead SOT-23 package, making it ideal for space-constrained applications such as cellular phones, wireless modems, and other portable devices.
