Working Principles

The LM3565TLE/NOPB is a step-up converter that efficiently drives LEDs. It takes an input voltage ranging from 2.7V to 5.5V and boosts it to a higher voltage required by the LEDs. The output current can be adjusted using an external resistor connected to the ISET pin. The device supports both PWM and analog dimming control methods, allowing precise brightness adjustment.

The IC incorporates over-temperature protection, which shuts down the device if the temperature exceeds safe limits. This ensures reliable operation and prevents damage to the LEDs or the IC itself. The compact size of the LM3565TLE/NOPB makes it suitable for space-constrained designs where efficient LED driving is required.
