BD7F200UEFJ-LB
无需光耦的隔离型反激式转换器
本产品是能够保证向工业设备市场长期供应的产品，而且是非常适用于这些应用领域的产品。
本产品是不需要光耦的隔离型反激式转换器。为了获得由变压器隔离的稳定输出电压，不再需要以往应用中所需的光电耦合器或通过变压器的三次绕组组成的反馈电路，从而可以大大减少元器件数量，并可实现小型、高可靠性的隔离型电源应用。此外，通过采用ROHM自有的自适应导通时间控制技术，也不再需要以往方式所需的外置相位补偿器件，从而可以轻松实现高性能的隔离型电源应用。

特点：
- Guaranteed long time supply availability for
Industrial Applications. - No need for an optocoupler or a transformer tertiary
winding.
The output voltage can be set by two external
resistors and the transformer turns ratio. - Uses Original Adapted Type ON-Time Control Technology.
High-speed load response is realized and external
phase compensation parts are unnecessary. - Fixed switching frequency and low output ripple
- Highly efficient light load mode available (PFM
operation) - Shutdown / Enable Control
- Built-in N-Channel MOSFET
- Soft start function
- Output load compensation function
- Protection functions:
VIN Under Voltage Lock-Out (VIN UVLO)
Over Current Protection (OCP)
Thermal Shutdown Protection (TSD)
