Overview
The BD7J200HFN-LBTR is an isolated flyback converter IC with an integrated switching MOSFET, designed for industrial equipment power supplies. It operates at a maximum switching frequency of 400 kHz and supports input voltages from 8 V to 80 V. The device delivers up to 5 W output power at 24 V input and 10 W at 48 V input, with a typical switch current limit of 1.75 A. It features a compact HSON-8 package measuring 2.9 x 3.0 mm.
Feature Summary
- Eliminates the need for optocouplers and transformer tertiary windings by utilizing original adapted type technology that controls on-time.
- Reduces component count and enables miniaturization by removing the requirement for external phase compensation parts.
- Integrates a 120 V switching MOSFET along with protection functions including soft start, thermal shutdown, and over-current protection.
Applications
- Isolated power supplies for industrial equipment
- Compact high-reliability isolated power applications
Procurement Notes
Verify the specific suffix LBTR against official datasheets to confirm tape-and-reel packaging and quantity specifications. Ensure compatibility with industrial temperature ranges and voltage requirements before procurement. Cross-reference RoHS compliance status directly with manufacturer documentation.
Selection Notes
Select this component when designing isolated flyback converters requiring minimal external components. It is suitable for applications needing high reliability without optocoupler feedback loops. Consider the 400 kHz switching frequency and integrated MOSFET capabilities for space-constrained industrial designs.
Part Context
This part belongs to ROHM's series of isolated flyback DC/DC converters featuring integrated controllers. These devices are engineered to simplify power supply design by reducing the number of external components required for stable operation in industrial environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases or ROHM technical support for verified alternatives.
