NCL30059BDR2G Description

Short technical summary and product information.

The NCL30059BDR2G is a self-oscillating high-voltage MOSFET driver from On Semiconductor, primarily tailored for LED driver applications using a half-bridge topology. It supports LLC and LCC configurations, offering optimized wide-range control for Constant Current (CC) applications. Its proprietary 600V technology makes it suitable for bulk voltages utilized in 277V AC lighting applications.

 

The operating frequency can be adjusted from 25 kHz to 250 kHz using a single resistor. The device features adjustable brown-out protection, a 100 ms PFC delay timer, and fixed dead-time to reduce shoot-through current. It includes an internal 16V VCC clamp and internal temperature shutdown for protection.

 

This controller is available in a Pb-Free SOIC-8 package, suitable for surface mounting. It supports outdoor use with an operating temperature range of -40°C to +125°C (TJ). Typical applications include low-cost resonant converters, CV and CC LED drivers, and various LED lighting fixtures like wallpacks, bollards, high bays, and streetlights.

 

Key electrical specifications include a wide operating frequency range of 25 kHz to 250 kHz, a maximum bulk voltage of 600V, and efficiency up to 92%. It offers a low startup current of 50 uA maximum and a peak current sink/source drive capability of 1A/0.5A.
