ROHM BD7682FJ-LB | Demoboard BD7682FJ-LB-EVK-402
Low Noise Quasi-Resonant Control DC/DC converter IC for AC/DC Converter
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 400-690 V |
| Output 1 | 24 V / 1 A |
| IC revision | A |
Description
The BD768xFJ-LB series are Quasi-Resonant switching AC/DC converter for driving SiC (Silicon Carbide)–MOSFET. Using external switching MOSFET and current detection resistors provides a lot of flexibility in the design. Power efficiency is improved by the burst function and the reduction of switching frequency under light load conditions. This is the product that guarantees long time support in the Industrial market.
Features
- Quasi-resonant method（Maximum frequency control 120kHz）/Current mode
- Low power when load is light ( Burst operation) / Frequency reduction function
- VCC pin : under voltage protection / over voltage protection
- Leading-Edge-Blanking function
- Over-current protection (cycle-by-cycle)
- ZT trigger mask function
- ZT Over voltage protection
- AC voltage correction function
- Soft start
- Brown IN/OUT function
- Gate Clamp circuit
- MASK Function
