ICE2A0165 - Offline Switching Power Supply Current Mode Controller/800V CoolMOS Integrated 650V
Description The second-generation CoolSET™-F2 key offers several special improvements to meet the need for low power standby and protection functions. Reduced shifts in standby mode are used to reduce power consumption and support this mode with a stable output voltage. The limited frequency is reduced to 20kHz/21.5kHz to avoid noise. In case of failure mode open loop, overvoltage or overload due to short circuit in automatic restart device switch control mode, is the internal protection unit. By means of internal precision peak current limiting, the size of the transformer and auxiliary diodes can be reduced, resulting in more cost for the size of the overall system effectiveness.
Features • Rugged CoolMOS™ 650V/800V Avalanche • Few external components • Input VCC under voltage lockout • 67kHz/100kHz switching frequency • Maximum duty cycle 72%
