The IRS2980SPBF is a Buck LED driver IC designed for efficient LED lighting applications. It features hysteretic output current regulation, operating typically between 25 kHz and 120 kHz, which allows for tightly regulated average output current despite variations in line and load conditions. The device incorporates a high-voltage regulator capable of handling up to 450V, eliminating the need for an external VCC supply. This LED driver supports both analog and PWM dimming control, enabling brightness adjustment from 0 to 100% with a control signal range of 0 to 2V for analog or 3.3V to 5V for logic signals. The internal architecture minimizes the external component count, enhancing manufacturability and reliability. Additionally, the IRS2980SPBF includes built-in latch immunity and ESD protection, making it suitable for robust applications. Engineers considering this product will find it beneficial for projects requiring a compact, efficient, and reliable LED driver solution.
