Product Overview: LT3486EFE#PBF

The LT3486EFE#PBF is a versatile, dual-output, step-up DC/DC converter designed by Linear Technology, now part of Analog Devices. This high-performance component is ideal for driving LED arrays and is widely used in portable and industrial applications that require efficient power management solutions.

Key Features

• Wide Input Voltage Range: The device operates from a 2.5V to 16V input range, making it suitable for a variety of battery configurations and power supplies.
• Dual Independent Output Channels: Each channel can drive up to six white LEDs in series, providing a balanced and consistent light source for dual display panels or lighting applications.
• High Efficiency: With an efficiency of up to 85%, the LT3486EFE#PBF ensures minimal power loss and heat generation, extending battery life in portable devices.
• Internal Soft-Start: This feature limits inrush current during startup, providing a gradual increase in LED brightness and protection against current surges.
• Adjustable Frequency: The switching frequency can be adjusted from 330kHz to 2.1MHz, allowing designers to optimize the converter for size, efficiency, and performance.
• Open LED Protection: The device includes open LED protection that disables LED current if an open LED is detected, preventing damage to the remaining LEDs.

Applications

• Portable Lighting
• Automotive and Avionic Lighting
• Industrial Display Backlighting
• General Purpose Dual LED Strings

The LT3486EFE#PBF is housed in a thermally enhanced TSSOP-16 package, offering robust thermal performance and space-saving advantages.
