The LM3495MTCX is an IC (Integrated Circuit) component offered by Texas Instruments. It is a step-up DC-DC converter designed for driving up to 10 parallel white LEDs in series from a single Li-Ion cell. This versatile device provides various features that make it suitable for a wide range of applications.
One key feature of the LM3495MTCX is its wide input voltage range, which allows it to operate efficiently from a single Li-Ion cell, typically providing an input voltage range of 2.7V to 5.5V. This flexibility makes it compatible with a variety of battery-powered devices, ensuring efficient power management.
The IC incorporates a current-mode boost converter architecture, providing a constant current source for the LED backlighting. This constant current drive guarantees uniform brightness across all the LEDs, improving display quality and eliminating variations due to LED mismatches.
The IC also offers adjustable feedback control, allowing users to regulate the LED current according to their specific requirements. This adjustable current control feature makes the LM3495MTCX highly customizable, enabling it to meet different design needs.
In addition, the LM3495MTCX includes a built-in soft-start function, which reduces inrush current during startup, thereby preventing potential damage to the device or LEDs. This feature ensures a smooth power-up sequence when the circuit is initially energized, adding to the overall reliability of the system
