The Texas Instruments LV2843DDCR is a high-efficiency, wide input voltage range buck regulator. It operates with an input voltage range of 4 V to 40 V, making it suitable for a variety of industrial and automotive applications. The device can deliver an output current of up to 1 A.
Key features include a fixed 0.7-MHz switching frequency, which allows for the use of smaller external components. It also offers features such as overcurrent protection, fixed soft start, and UVLO (undervoltage lockout). The regulator has a low quiescent current of 30 µA typical, which helps in prolonging battery life.
The LV2843DDCR is available in a compact SOT-23-THN package, measuring 2.9 mm x 2.8 mm with an area of 8.12 mm². This small footprint, combined with internal compensation and soft start, simplifies design and reduces overall solution size.
