Key Featrues
Up to 96% Efficiency - The LTC3429/LTC3429B achieves up to 96% efficiency, significantly reducing power loss and extending battery life in portable devices such as MP3 players, GPS receivers, and wireless handsets. This high efficiency is particularly beneficial in low-power applications where energy conservation is critical.
True Output Load Disconnect - This feature ensures complete isolation of the output from the input when the device is in shutdown mode, preventing any leakage current and enhancing safety and reliability in applications like handheld instruments and digital cameras.
Inrush Current Limiting and Internal Soft-Start - The built-in inrush current limiting and soft-start functionality minimize stress on components during startup, improving the longevity of the device and ensuring smooth operation in systems such as LCD bias supplies and other sensitive electronics.
Low Voltage Start-Up: 0.85V - The ability to start up at a low voltage of 0.85V makes the LTC3429/LTC3429B ideal for single-cell or low-voltage applications, such as AA battery-powered devices, ensuring reliable performance even when the battery is nearly depleted.
Automatic Burst Mode® Operation with IQ ~ 20µA - In light load conditions, the device automatically switches to Burst Mode, reducing quiescent current to approximately 20µA. This feature enhances efficiency in low-power scenarios, making it suitable for energy-sensitive applications like wireless sensors and portable electronics.
