Overview
The BD7J201EFJ-LBE2 is a low power isolated flyback converter IC manufactured by Rohm Semiconductor. It integrates a switching MOSFET and operates with an input voltage range of 8 V to 80 V. The device provides a single output at 120 V with a fixed switching frequency of 400 kHz. It is housed in an HTSOP-J8 package and supports surface mount installation. The component functions within a temperature range of -40 °C to +125 °C.
Feature Summary
- Integrates a switching MOSFET for compact design
- Provides galvanic isolation via flyback topology
- Operates without external optocouplers
Applications
- Isolated DC-DC conversion in industrial equipment
- Power supplies for appliances requiring high voltage isolation
- Offline converter applications in consumer electronics
Procurement Notes
Verify the exact suffix LBE2 against the manufacturer's current datasheet to confirm packaging type and tape/reel specifications. Ensure the HTSOP-J8 footprint matches your PCB layout constraints. Confirm RoHS compliance status directly from the official documentation before procurement.
Selection Notes
Select this component when a high-voltage isolated output is required from a wide DC input range. The integrated MOSFET simplifies the bill of materials compared to discrete solutions. Consider the 400 kHz switching frequency for balancing efficiency and passive component size in flyback designs.
Part Context
This part belongs to Rohm's BD7J series of isolated flyback converters. These devices are designed for low-power applications where space savings and reduced component count are critical. The series typically features high integration levels, including internal drivers and protection circuits, to facilitate easy implementation in offline power supply designs.
Replacement Considerations
Check for direct pin-compatible substitutes within the BD7J series, such as the BD7J101EFJ-LBE2, which shares similar electrical characteristics and packaging. Verify that any alternative maintains the same 120 V output capability and 400 kHz switching frequency.
