IRS2980S Product details

Description
The IRS2980S utilizes International Rectifiers control and high-voltage technologies to realize a simple, high-performance Buck LED driver solution. This solution is based on hysteretic output current regulation typically operating from 25 kHz to 120 kHz. Frequency and duty cycle vary to maintain a tightly regulated average output current over variations in line and load. Output current ripple will depend on inductor selection in conjunction with input and output voltages as well as output current and component selection. The IRS2980S uses a unique floating high side differential current sense and level shift scheme allowing hysteretic operation with a low side switching MOSFET optimizing size and cost. In addition, the IRS2980S includes a high voltage regulator able to operate up to 450V eliminating the need for an external VCC supply. A PWM dimming interface is also included that can be controlled from a 0 to 2V analog or 3.3 or 5V logic control signal able to operate up to 1kHz offering brightness control from 0 to 100%. A programmable on board PWM oscillator is used with DC dimming control.

About International Rectifier


International Rectifier (IR) was an American company that specialized in the design and manufacture of power management and power control semiconductors.
The company was founded in 1947 and was headquartered in El Segundo, California.
IR provided a wide range of products including power management ICs, power MOSFETs, IGBTs, and other power control products.
The company's products were used in various applications such as computing, telecommunications, and industrial automation.
IR was known for its expertise in power management and control technology and its ability to deliver high-quality and reliable products to its customers.
In 2014, IR was acquired by Infineon Technologies, a leading provider of power management and control products and other semiconductor solutions.
The International Rectifier brand is no longer in use, but its technology and products continue to be a part of Infineon's portfolio.
