Datasheet 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 Operating Power Supply Voltage Range: Industrial market. VCC 15.0V to 27.5V BD768xFJ series is a Quasi-resonant controller type Normal Operating Current: 0.80mA(Typ) DC/DC converters that provide an optimum system for Burst Operating Current: 0.50mA(Typ) all products that include an electrical outlet. Maximum Frequency: 120kHz(Typ) Quasi-resonant operation enables soft switching and Operating Temperature: -40C to +105C helps to keep EMI low. Design with a high degree of flexibility is achieved with switching MOSFETs and current detection resistors as external devices. Package 4.90mm x 6.00mm x 1.65mm pitch 1.27mm The built-in brown out function monitors the input (Typ.) (Typ.) (TYP.) (TYP.) 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. BD768xFJ series include a gate-clamp circuit for optimal driving SIC-MOSFET. SOP-J8 Features 4.90mm x 6.00mm x 1.65mm Pin 8 : SOP-J8 Package (6.00mm 4.90mm : 1.27mm pitch <TYP>) Quasi-resonant type (low EMI) Frequency reduction mode Low current consumption (19A), during standby Lineup Low current consumption when no load (burst FBOLP VCCOVP operation when light load) BD7682FJ AutoRestart Latch Maximum frequency (120kHz) BD7683FJ Latch Latch CS Pin Leading-Edge Blanking BD7684FJ AutoRestart AutoRestart VCC UVLO (Under Voltage Drop Out protection) BD7685FJ Latch AutoRestart VCC OVP (Over Voltage Protection) Per-cycle over-current protection circuit Soft start Applications ZT trigger mask function Industrial equipment, AC Adaptor, Household appliances Voltage protection function (brown out) ZT OVP (Over Voltage Protection) Gate-clamp circuit Typical Application Circuit FUSE Diode Filter Bridge 8 7 6 5 BO VCC MASK OUT ERROR AMP ZT FB CS GND 2 3 4 Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays .w ww.rohm.com TSZ02201-0F1F0A200050-1-2 2015 ROHM Co., Ltd.
