The LT3494EDDB is a compact, high-performance integrated circuit designed by Linear Technology, now part of Analog Devices, that serves as a micropower step-up DC/DC converter with integrated Schottky diode and output disconnect. This product is specifically tailored for driving light-emitting diodes (LEDs) from a single cell Lithium-Ion battery, making it an ideal choice for portable lighting and backlighting applications.

Key Features:

• Integrated Schottky Diode: The LT3494EDDB comes with an integrated Schottky diode, which helps in reducing the overall component count and simplifying the circuit design.
• Output Disconnect: The output disconnect feature ensures that the output is isolated from the input when the device is in shutdown mode, preventing leakage currents through the LEDs when the device is off.
• Wide Input Voltage Range: This converter operates over a wide input voltage range from 2.5V to 16V, accommodating a variety of power sources.
• High Efficiency: With its high switching frequency of up to 2.1MHz, the LT3494EDDB allows the use of small inductors and capacitors, resulting in a compact solution with high power efficiency.
• Adjustable Output Voltage: The output voltage is adjustable up to 34V, which is suitable for driving multiple LEDs in series, providing consistent brightness and performance.

Applications:

• Portable LED Lighting
• LED Backlighting for LCD Displays
• Optical Indicators
• Photoflash and Strobe Lighting

The LT3494EDDB is available in a small 6-pin DFN package with a low profile of just 0.75mm, which is excellent for space-constrained applications. Its thermal performance is optimized for LED driving scenarios, ensuring reliability and longevity of the solution. Designers looking for a versatile, efficient, and compact LED driving solution will find the LT3494EDDB to be an excellent choice.
