SSL21151T/1,118 Integrated Circuits (ICs)

SSL21151T/1,118 is a PMIC - LED Drivers specifically designed to control LEDs. It is a three-channel driver with one constant current source for each channel, enabling up to three LEDs to be powered up individually and operated in series or parallel connection. The constant current source provides a stable yet flexible current to each LED, enabling the design of various types of LED string illumination. The high level of integration integrates a 2.2 - 2.6V voltage regulator, a low quiescent current device and a logic level shift mechanism into a single 8 pin TDFN package.

The SSL21151T/1,118 has an operating voltage range of 1.8 V to 4.5 V and a maximum output current of 350 mA. The built-in voltage regulator can operate in a wide range, achieving a good balance between the input voltage and output current. It is also designed to be power efficient, reducing power consumption by up to 25%. It features three input pins and three output pins that can be adjusted independently. The output current can be adjusted in fine steps of 0.2 mA, enabling precise control of LED intensity.

The SSL21151T/1,118 has two operation modes: linear mode and PWM mode. Linear mode regulates the output current linearly according to a set input voltage. PWM mode allows for the adjustment of brightness without altering the output current. It is an ideal solution for mobile devices, and its light weight, low profile and low heat emissions make it an attractive solution for mobile applications.

The SSL21151T/1,118 is also designed for easy integration into PCB or other circuits. It has a low input capacitance which reduces the power requirements of a device, and the wide operating range makes it suitable for a variety of applications. The device is also compliant with the RoHS directive. It is safety certified, including CSA and UL, thus ensuring the safe operation of the device in its intended application area.

Overall, the SSL21151T/1,118 is a great choice for LED drivers in mobile and portable applications. Its wide operating range, low input capacitance and low quiescent current make it an ideal solution for cost-effective implementations. With its built-in voltage regulator, fine current adjustment and two operation modes, the device offers a lot of flexibility and performance in one small package.
