The LTC3862HUH#TRPBF is a high voltage current mode synchronous step-up DC/DC controller designed for driving one or more LEDs in series. It is manufactured by Linear Technology, now part of Analog Devices. This integrated circuit (IC) component is widely used in applications such as LCD monitors, automotive lighting, industrial lighting, and general-purpose LED lighting.
One of the primary features of the LTC3862HUH#TRPBF is its high input voltage range, which can operate from 3V to 40V. This allows it to handle a wide range of input sources such as batteries, automotive power systems, and industrial power supplies. The high voltage capability makes it suitable for various lighting applications.
The IC employs a current mode control architecture, which provides excellent line and load regulation. Its current mode control ensures stable and accurate LED current, even in the presence of input voltage fluctuations or load variations. This helps in minimizing LED brightness fluctuations and provides consistent illumination.
The LTC3862HUH#TRPBF can deliver a maximum LED current of 1.4A, making it suitable for powering high-brightness LEDs. The IC supports both step-up (boost) and step-down (buck) operation, allowing flexibility in LED string configurations. This versatility enables driving LED strings with different forward voltage drops, making it suitable for illuminating diverse LED arrays.
Another key feature of this IC is its built-in diagnostics and protection features
