LCS702HG
Integrated LLC Controller, High-Voltage Power MOSFETs and Drivers
Applications
Product Details
Description
The HiperLCS IC is an integrated LLC power stage incorporating a multi-function controller, high-side and low-side gate drivers, plus two power MOSFETs in a half-bridge configuration. Figure 1 (above) shows a simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer.
Product Highlights
Features
- LLC half-bridge power stage incorporating controller, high and low-side gate drives, and high-voltage power MOSFETs
- Eliminates up to 30 external components
- Reduces assembly cost and reduces PCB layout loop areas
- High maximum operating frequency of 1 MHz
- Dramatically reduces magnetics size and allows use of SMD ceramic output capacitors
- Comprehensive fault handling and current limiting
