Key Featrues
Integrated Schottky Diode: The LT3473 includes an integrated Schottky diode, which reduces external component count and simplifies PCB design. This integration enhances efficiency by minimizing power losses typically associated with external diodes, making it ideal for compact and high-performance applications like portable electronics.
Micropower Operation with Low Quiescent Current: With a quiescent current of just 150µA in active mode and 1µA in shutdown mode, the LT3473 is optimized for battery-powered devices. This feature significantly extends battery life, making it suitable for applications such as wireless sensors and IoT devices where power efficiency is critical.
Internal 1A, 36V Switch: The internal 1A switch allows the LT3473 to deliver high output voltages (up to 36V) with minimal external components. This feature enables the converter to handle demanding loads, such as biasing OLED displays or CCD sensors, while maintaining a compact solution size.
Automatic Burst Mode® Operation: The LT3473 automatically enters Burst Mode® operation under light load conditions, improving efficiency by reducing switching losses. This feature is particularly beneficial for applications with varying load demands, such as wearable devices, where maintaining efficiency across different usage scenarios is essential.
Output Disconnect Circuitry: The integrated PNP output disconnect ensures that the output is completely isolated from the input during shutdown, preventing any leakage current. This feature is crucial for applications like energy harvesting systems, where preserving energy during idle periods is paramount.
