NCL30059中文资料LED Driver, High-Voltage Half-Bridge Controller数据手册ONSEMI规格书

描述 Description

The NCL30059B is a self−oscillating high voltage MOSFET driver
primarily tailored for LED driver applications using half−bridge
topology. LLC and LCC configurations are supported with optimized
wide range control offered by the latter for Constant Current (CC)
applications. Due to its proprietary 600 V technology, the driver is
useful for bulk voltages utilized in 277 VAC lighting applications.

特性 Features

• Wide operating frequency range from 25 kHz to 250 kHz
• Wide Input and output driving range
• Minimum frequency adjust accuracy 3 %
• Keeps the converter in the right region & simplifies design
• 100 ms PFC delay timer
• Allows PFC bulk voltage to stabilize before device operation
• Adjustable Brown-out
• Simple PFC association, design flexibility
• Dead Time − 0.6 µs
• Prevents shoot-through currents and allows body diode to discharge
• Internal 600 V Half bridge gate driver
• High Input voltage operating capability - 277/ 305 VAC
• PSR current regulation ± 2%
• Uniform luminous intensity with low eBOM

应用 Application

• LED Electronic Control Gear
• LED Driver Power Supplies
• Power Supplies for LED Signage
• AC-DC Low Ripple LED Drivers
• LED Luminaires

简介

NCL30059属于集成电路（IC）的LED驱动器。由制造生产的NCL30059LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
