Key Featrues

2.5A, 40V Internal Switch: The LT3489 integrates a high-current, high-voltage internal switch capable of handling up to 2.5A and 40V. This feature ensures robust power delivery, making it ideal for applications like TFT-LCD bias supplies and GPS receivers, where high efficiency and reliability are critical.
2MHz Switching Frequency: The fixed 2MHz switching frequency allows the use of compact, low-profile inductors and ceramic capacitors. This results in a smaller overall footprint, making the LT3489 suitable for space-constrained designs while maintaining high efficiency and fast transient response.
Integrated Soft-Start Function: The soft-start feature, controlled by an external capacitor, ensures a gradual ramp-up of input current during startup. This prevents inrush current issues, enhances system stability, and prolongs the lifespan of components in applications like DSL modems and local power supplies.
Wide Input Voltage Range (2.6V to 16V): The LT3489 supports a broad input voltage range, enabling it to operate efficiently from low-voltage sources like batteries or regulated power supplies. This versatility makes it suitable for portable devices and systems requiring flexible power solutions.
Adjustable Output Voltage (Up to 40V): The adjustable output voltage, ranging from the input voltage up to 40V, provides design flexibility for various applications. This feature allows precise voltage regulation, ensuring optimal performance in powering high-voltage components like TFT-LCD panels or other specialized loads.
