描述 Description

Off-Line SMPS Current Mode Controller with integrated 800V CoolMOS? and Startup cell (input OVP & frequency jitter) in DIP-7
The ICE3AR1080VJZ is a modified version of ICE3ARxx80JZ (CoolSET?-F3R 800V) in DIP-7 package. It adds in the input OVP feature but removes the brownout feature and external protection enable feature. In summary, the ICE3AR1080VJZ is a device running at 100kHz, implemented with input OVP feature, installed with 800V MOSFET with startup cell and housed in DIP-7 package. It provides good voltage margin of MOSFET, lowest standby power, selectable burst level, reduced output ripple during burst mode, robust protection with input OVP feature, accurate maximum power control for both maximum power and burst power, low EMI with frequency jittering and soft gate drive, built-in and flexible protections, etc.
