The LT3491SC8TRPBF is a high-performance, fixed frequency step-up DC/DC converter designed by Linear Technology, now part of Analog Devices. This compact and efficient integrated circuit is housed in an SC-70 package, optimized for space-constrained applications. It is an ideal solution for portable devices due to its low quiescent current and high efficiency over a wide input voltage range.

Key Features:

• Wide Input Voltage Range: The device is capable of operating from an input voltage as low as 2.5V and up to 16V, making it suitable for single-cell Li-Ion, multi-cell alkaline, or NiMH applications, as well as fixed 3.3V or 5V systems.
• Adjustable Output Voltage: The output voltage is adjustable up to 34V, which allows for versatility in various designs and applications.
• High Switching Frequency: A switching frequency of 1.2MHz allows the use of small, low-cost capacitors and inductors, reducing the overall footprint of the power supply design.
• Integrated Boost Diode: The inclusion of an integrated Schottky diode simplifies the design and minimizes external component count, which can be beneficial for space-constrained applications.
• Low Quiescent Current: With a quiescent current of only 2.8μA, the LT3491SC8TRPBF ensures high efficiency, particularly important for battery-powered devices.

Applications:

• Portable Power Devices
• Handheld Instruments
• Battery-Powered Equipment
• Small LCD Displays
• LED Drivers

The LT3491SC8TRPBF is a robust and reliable choice for designers looking to implement a compact power solution without compromising on performance.
