The LM3554TMX/NOPB is an integrated double-string LED driver designed for driving dual-string white LEDs with brightness control. It can be easily configured for either buck or boost operation, depending on the voltage source and LED string. It utilizes a 1-MHz step-down converter with 63% peak efficiency, a linear regulator for string accuracy, and I2C communication interface for easy integration into designs.
The device is suited for a wide range of applications in which the value of energy savings and extended operating times are desired. Typical applications include various types of LED video screens, automotive dashboard and interior lighting, stadium lighting, handheld projectors, and industrial lighting.
The LM3554TMX/NOPB is integrated with an LED driver that consists of two LED string drivers. The LED output is controlled with an I2C register, which provides accurate control over the LED string current. In addition, the device includes voltage regulation, dynamic gain control, and thermal shutdown protection.
The LM3554TMX/NOPB supports both boost and buck operation. In boost mode, the device will regulate the LED string current while the voltage is supplied to the LED. In buck mode, the device will regulate the LED string current while the voltage is supplied from the LED. The LED output is controlled using an I2C interface, which provides access to a number of programmable features, including LED string current, LED brightness, LED turn-off point, and LED current decay.
The LM3554TMX/NOPB is designed for low-power applications, where it is capable of providing up to 4A of continuous current to the two LED strings. The maximum output voltage rating of the device is 35V, which makes it suitable for operating a wide range of LED strings. The device features a wide operating junction temperature range from -40°C to +130°C and a maximum output current of 4A.
The LM3554TMX/NOPB is a complete solution for driving dual-string white LEDs with brightness control. It provides integrated regulated string current control, dynamic gain control, I2C interface, and thermal protection. It supports both buck and boost operations and can be easily configured for both operations. With its wide operating temperature range and 4A maximum continuous output current, the LM3554TMX/NOPB is suitable for a variety of applications which require energy-savings and extended operating times.
