Technical Specifications

The ICE2PCS04 typically operates with a wide input voltage range (e.g., 85-265 VAC). It features active burst mode operation to achieve very low standby power consumption, typically less than 100mW. The integrated CoolMOS™ MOSFET ensures high efficiency and low switching losses. The device incorporates comprehensive protection features, including over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP), safeguarding the power supply from potential damage. Frequency jittering helps to reduce EMI emissions, simplifying compliance with regulatory requirements. Check the specific datasheet for detailed electrical characteristics and application guidelines.
