The LT3465ES6#TRMPBF is a member of the PMIC - LED drivers family. It provides power switching, over temperature protection, and adjustable current limiting to effectively regulate an output current up to 1A. The integrated MOSFET, power-good comparator, over-temperature shutdown, and current sensing comparator make it ideal for cost sensitive applications. Applications include cell phones, PDAs, MP3 players, and hand-held electronic devices.

The LT3465ES6#TRMPBF provides an adjustable current limit of up to 1A, independent of output voltage. Additionally, the device has a wide operating voltage range of 2.3V to 5.5V, making it suitable for practically any portable device. It features an over-temperature shut down to protect the device from possible damage due to thermal conditions. The current limit is adjustable through the current sense pin via an external resistor.

The LT3465ES6#TRMPBF also comes with a “Power Good” output signal that allows the controller to detect when the device has reached a valid output voltage level. Once this voltage is passed, the power-good signal is sent to the host system to enable digital control of multiple LEDs. The device also comes with a number of additional protection features, such as thermal shutdown and short-circuit protection.

The LT3465ES6#TRMPBF makes use of the “linear mode,” where feedback sensing within the device controls output current and voltage to ensure stable output regulation regardless of variations in input voltage, temperature, or output capacitance. The device also has a “burst mode” mode of operation which allows it to run in a burst /low power mode to reduce power dissipation when the load is light.

The LT3465ES6#TRMPBF is also capable of effective drive switching for output voltages up to 20V. It features a fast response time of 5ns and a low output voltage noise of 4mV. The device is available in a thermally-enhanced, space efficient 6-pin TDFN package. Its high efficiency, fast transient response and low quiescent current make it perfect for use in battery-powered applications.

Overall, the LT3465ES6#TRMPBF is an ideal LED driver solution for cost-sensitive, portable device applications. It provides lot of features and protection along with fast switching capabilities and adaptive output regulation, as well as low power consumption and an efficient, space-saving package.
