LP3954RL/NOPB

PMIC (power management integrated circuits) are capable of managing the power supply and promotion of a wide variety of applications. Among them, LED drivers are just one kind. LP3954RL/NOPB is a highly integrated power management IC with many functions and significant performance in the field of LED drivers.

The LP3954RL/NOPB can drive three strings of LEDs with up to 18 LEDs per string, providing adjustable current. It can drive up to 54 LEDs with a current up to 150mA. The wide range of current that it provides makes it suitable for a large number of LED applications such as general lighting, street lights, commercial lighting, automotive and more. Besides, it also offers a high level of protection including temperature and over-current/voltage protection.

The LP3954RL/NOPB employs an advanced voltage mode drive technology for maximum efficiency and long life. This type of drive technology is designed to minimize the power dissipated in the LED string and maintain a constant LED current over a wide range of LED voltages. This ensures a uniform LED intensity over a broad dynamic range. Moreover, the high accuracy of the current regulation ensures uniform and reliable performance of the LEDs.

The integrated over-current/voltage protection circuit of the LP3954RL/NOPB can effectively prevent the LEDs from excessive current or voltage. It can also protect the device itself and maintain its stable operation. The temperature protection circuit can accurately detect and report the die temperature, providing protection against thermal runaway of the device and preventing damage to the LEDs due to excess temperature.

The LP3954RL/NOPB is available in a 5x5mm QFN package, making it an ideal choice for space-constrained applications. The low operating power also makes it suitable for portable lighting applications such as flashlights. The wide range of applications and the high-performance offered by the LP3954RL/NOPB make it an ideal choice for LED drivers.
