General Description

This product guarantees long time supply availability in

the industrial instrumentation market.

BD7F200 is an optocoupler-less Isolated Flyback

Converter. An optocoupler or the tertiary winding

feedback circuit which was needed to obtain a stable

output voltage isolated by a transformer in the

conventional application becomes unnecessary, thus,

the number of parts is reduced drastically, producing a

small-sized and high-reliability application isolated type

power supply.

Furthermore, a highly by the use of the Original

Adapted-Type ON-Time Control Technology, it makes

the external phase compensation parts become

unnecessary, therefore a highly efficient isolated type

power supply application can easily be produced.

Features

? 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)

Application

? Industrial equipment Isolated Power Supply
