描述
本产品是能够保证向工业设备市场长期供应的产品，是不需要光耦的隔离型反激式转换器。使用本产品，将不再需要以往应用中为了获得稳定的输出电压而需要的由光电耦合器或变压器辅助绕组组成的反馈电路。此外，通过采用ROHM自有的自适应导通时间控制技术，也不再需要外置相位补偿器件，从而可以使隔离式电源设计所需的元器件数量显著减少，并且能够实现小型化和更高可靠性。

Low Power Isolated Flyback Converter IC

with Integrated Switching MOSFET

BD7J101HFN-LB (Under Development) BD7J101EFJ-LB

General Description

Key Specifications

This is the product guarantees long time support in

Industrial market.

◼ Power Supply Voltage Range

VIN Pin:

8 V to 80 V

120 V (Max)

0.90 A (Typ)

400 kHz (Typ)

±1.6 %

This IC is an optocoupler-less isolated flyback converter.

It is not necessary to use any optocouplers and feedback

circuits by a third winding of transformers; these have

been ever required to obtain a stable output voltage in

conventional applications. Furthermore, adoption of the

original adapter type technology that controls on time

makes the external phase compensation parts

unnecessary, which realizes the designs of isolated

power supply application with drastic reduction of parts

number, minimization of application circuits, and high

reliability.

SW Pin:

◼ Over Current Protection Current:

◼ Switching Frequency:

◼ Reference Voltage Accuracy:

◼ Current at Shutdown:

◼ Current at Switching Operation:

0 μA (Typ)

0.45 mA (Typ)

◼ Operating Temperature Range: -40 °C to +125 °C
