Product Description
The ICE3BR4765J is an off-line SMPS current mode controller from Infineon's CoolSET®-F3R jitter series, integrating a 650V CoolMOS® power switch and Startup cell into a compact PG-DIP-8 package. It's designed for off-line battery adapters and low-cost, lower-power SMPS applications such as DVD/Blu-ray players and set-top boxes.
Building on the earlier CoolSET®-F3 series, it adds built-in soft start time, a built-in blanking window, built-in frequency jitter, and soft gate driving, while retaining active burst mode and auto-restart protection for improved efficiency and reduced standby power.
