Adjustable CCRs for LED Lighting Applications

ON Semiconductor has expanded its portfolio of adjustable Constant Current Regulators. The new CCRs, which provide voltage surge suppression to protect general lighting and automotive LEDs, are simple and highly robust devices designed to provide cost-effective current regulation to LEDs. They are based on the company’s proprietary, patent-pending Self-Biased Transistor technology and regulate current over a wide voltage range.

ON Semiconductor’s new compact CCR devices eliminate the need for additional regulation within the system design. They offer engineers a highly effective LED protection solution that supports tight application budgets and development schedules.

The NSI45090JDT4G and NSI45060JDT4G are offered in D-PAK packages and priced at $0.16 per unit in 10,000 unit quantities. The NSI45020JZT1G and NSI45035JZT1G are offered in SOT-223 packages and priced at $0.10 per unit in 10,000 unit quantities. These devices are all AEC−Q101 qualified. All of the CCRs are offered in compact, thermally robust, RoHS-compliant packages, made using a halogen-free molding compound and lead free lead finish and have an operating temperature range of −55 °C to +150 °C.
