Low Noise Quasi-Resonant Control

DC/DC converter IC for AC/DC Converter

BD7682FJ-LB BD7683FJ-LB BD7684FJ-LB BD7685FJ-LB

General Description

Key Specifications

This is the product guarantees long time support in the

Industrial market.



Operating Power Supply Voltage Range:

VCC 15.0V to 27.5V

0.80mA(Typ)

BD768xFJ series is a Quasi-resonant controller type

DC/DC converters that provide an optimum system for

all products that include an electrical outlet.

Quasi-resonant operation enables soft switching and

helps to keep EMI low. Design with a high degree of

flexibility is achieved with switching MOSFETs and

current detection resistors as external devices.

The built-in brown out function monitors the input

voltage as part of system optimization. The burst mode

function reduces input power at low power.

BD768xFJ series include various protection functions,

such as a soft start function, burst function, per-cycle

over-current limiter function, overvoltage protection

function, overload protection function, and brown out

function.



Normal Operating Current:

Burst Operating Current:

Maximum Frequency:

0.50mA(Typ)

120kHz(Typ)

-40°C to +105°C

Operating Temperature:
