ROHM SCT2H12NZ | Demoboard BD7682FJ-LB
BD768xFJ-LB series Quasi-Resonant converter Technical Design 24V / 1A ( SIC TO-3PFM SCT2H12NZ)
Overview
| Topology | Flyback Converter |
| Input voltage | 400-690 V |
| Output 1 | 24 V / 1 A |
| IC revision | Rev. A |
Description
The BD768xFJ-LB series are Quasi-Resonant switchingAC/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 modeLow power when load is light ( Burst operation) / Frequency reduction functionVCC pin : under voltage protection / overvoltage protectionLeading-Edge-Blanking functionOver-current protection (cycle-by-cycle)ZT trigger mask functionZT Over voltage protectionAC voltage correction functionSoft startBrown IN/OUT functionGate Clamp circuitMASK Function
Typical applications
- Industrial equipment, AC Adaptor, Household appliances
