NCL30288BSNT1G Description

Short technical summary and product information.

The NCL30288BSNT1G from ON Semiconductor is a compact driver designed for power-factor-corrected flyback, non-isolated buck-boost, and SEPIC converters. It operates in a quasi-resonant mode for optimal efficiency and utilizes a proprietary control method for tight LED current regulation from the primary side, eliminating the need for secondary-side feedback circuitry and optocouplers.

 

This highly integrated device is housed in a TSOP-6 package, requiring a minimum number of external components. It features robust protection mechanisms including OVP on VCC, programmable over-voltage/LED open circuit protection, cycle-by-cycle peak current limit, winding short circuit protection, secondary diode short protection, output short circuit protection, thermal shutdown, VCC undervoltage lockout, and brown-out detection.

 

Typical applications include integral LED bulbs and tubes, LED light engines, and LED drivers/power supplies. The device is optimized for wide-range line applications and offers line feedforward for enhanced regulation accuracy. It supports a wide VCC range and includes a 300 mA / 500 mA totem pole driver with a 12 V gate clamp.
