Onsemi NCL30159 | Demoboard LED-SMART-DIM-LLC-150WGEVB
Wide Dimming Current Mode LLC Half Bridge Controller for LED Lighting
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 90-264 V |
| Output 1 | 50 V / 3 A |
| IC revision | A |
Description
The NCL 30159 is a primary side current mode LLC controller. The controller can provide wide dimming range operation in wide output condition. This controller allows to implement many features (high efficiency in standby, open string protection, dedicated startup). And allows to ensure the maximum power limit feature. It enable to design the wide input voltage range converters or the LED drivers with their output matched to different LED strings.
Features
- Integrated High−Voltage Startup Circuit with Brownout Detection
- High−Frequency Operation from 20 kHz up to 750 kHz
- Current Mode Control Scheme
- Automatic Dead−time with Maximum Dead−time Clamp
- Over Current and Open String Protection
- Shorted LED String Protection
- Proprietary Skip Cycle in No−load Operation
- Dedicated Soft Start Sequence to Avoid Hard Switching
- This is a Pb−Free Device
Typical applications
- Low-Cost High Efficiency LED Lighting 50 ~ 300 W
- EV Battery Charger
- TV Set Power Supply
