Product Overview: LT3486IFE#TRPBF
The LT3486IFE#TRPBF is a high-performance, dual-output, step-up DC/DC converter designed by Linear Technology, an industry leader in analog integrated circuits. This component is specifically engineered to drive light-emitting diodes (LEDs) and is ideal for portable and compact applications where efficient power management is crucial.
Featuring independent internal power switches for each channel, the LT3486IFE#TRPBF can drive up to eight white LEDs from a single Li-Ion cell with each channel capable of driving up to four LEDs in series. This flexibility allows for a wide range of design options and can cater to various lighting requirements.
The device operates with a switching frequency of 2MHz, which allows for the use of small, low-profile inductors and ceramic capacitors, thus reducing the overall footprint of the power supply on the circuit board. The high switching frequency also contributes to a lower ripple in the LED current, ensuring consistent light output.
One of the key features of the LT3486IFE#TRPBF is its high efficiency, which is achieved through the use of a 36V, 1.3A internal switch with an RDS(ON) of just 0.2 ohms. This low on-resistance switch minimizes power loss and helps in maintaining a high efficiency over a wide range of load conditions.
The device also includes a unique True Color PWM™ dimming capability, which provides up to 3000:1 color dimming ratio. This allows for precise control over LED brightness while maintaining color fidelity, which is especially important in applications where color consistency is critical.
For protection, the LT3486IFE#TRPBF incorporates features such as open LED protection, short-circuit protection, and thermal shutdown. These protective measures ensure the longevity and reliability of the device under adverse conditions.
Available in a thermally enhanced 16-lead TSSOP package, the LT3486IFE#TRPBF is designed to perform in a wide temperature range, making it suitable for various industrial and automotive applications. Its robust design and high-performance capabilities make it an excellent choice for designers looking to enhance the efficiency and functionality of their LED driving solutions.
