Description

The ICE2A280Z is a second generation CoolSET™-F2 electronic component model. It offers several enhancements to address the requirements for low power standby and protection features. The device uses frequency reduction in standby mode to lower power consumption while maintaining a stable output voltage. This reduction is limited to 20kHz/21.5 kHz to avoid audible noise. Additionally, the ICE2A280Z features an auto restart mode for protection against failure modes such as open loop, overvoltage, or overload due to short circuit. The internal protection unit controls this mode. Precise peak current limitation offered by the device allows for lower sizing of the transformer and secondary diode, resulting in a more cost-effective overall system.
