3BR4765JZ Datasheet – Off-Line SMPS Current Mode Controller

Part Number: 3BR4765JZ, ICE3BR4765JZ

Function: Off-Line SMPS Current Mode Controller with integrated 650V CoolMOS

Package: DIP 7 Pin

Manufacturer: Infineon Technologies AG

3BR4765JZ Infineon controller


3BR4765JZ is derived from ICE3BR4765J in DIP-7 package. The CoolSET®-F3R jitter series (ICE3BRxx65J) is the latest version of CoolSET®-F3. It targets for the Off-Line battery adapters and low cost SMPS for lower power range such as application for DVD R/W, DVD Combi, Blue ray DVD player, set top box, etc. Besides inherited the outstanding performance of the CoolSET®-F3 in the BiCMOS technology, active burst mode, auto-restart protection, propagation delay compensation, etc., CoolSET®-F3R series has some new features such as built-in soft start time, built-in blanking window, built-in frequency jitter, soft gate driving, etc. In case a longer blanking time is needed for high load application, a simple addition of capacitor to BA pin can serve the purpose. Furthermore, an external auto-restart enable feature can provide extra protection when there is a need of immediate stop of power switching.
