PMIC - LED Drivers

The LM3554TME/NOPB is a PMIC - LED Drivers special designed to operate two high power LEDs. It can operate in a wide range of UV applications, including UVB, UVA, and white illumination. This device has dual channels of operation that can provide up to 10W of LED power.

The LM3554TME/NOPB is capable of driving both low and high power LEDs. It features a current regulation of up to 700mA per channel and up to 100mA for each LED. The device can be enabled using either a PWM input, a single direction output, or the LM3554TME/NOPB itself.

The LM3554TME/NOPB has an adjustable low-side output current limiting and overtemperature protection, an adjustable low-current LED voltage of 1.8V and a breakdown voltage of 4.3V. It has a shutdown capability, allowing the user to turn off the device’s LED channels when the application is not in use. The device has a wide input voltage range of 2.7V to 12V, allowing for a wide range of applications.

The LM3554TME/NOPB offers a pin-selectable constant current regime, allowing the user to select a low current or high power operation. The device’s low-side current limiting automatically adjusts and maintains the current as the LEDs’ temperature changes, protecting the LEDs from damage. The device also features thermal shutdown, overvoltage protection, over-current protection, and an over-temperature protection for improved safety.

The LM3554TME/NOPB is a high power LED driver with a wide range of applications. Its wide input voltage range, adjustable currents, and thermal protections make it an ideal choice for applications such as UV curing, disinfection, UV printing, or any other UV or White LED applications. It is available in both surface mount and through-hole packages, making it suitable for various LED systems.
