IW1820
15W AccuSwitch™ AC/DC Digital Primary-Side Switcher Eliminates Optocoupler and Maintains Excellent Cross-Regulation Accuracy
72KHz集成800V BJT优化5VOUT
IW1820AccuSwitch™digital PWM controller integrates a highly accurate control circuit with an 800V BJT power switch to provide a complete solution for off-line power conversion at up to 15W of output power.
对话框primAccurate™primary-side digital control algorithms eliminate the need for failure-prone optocouplers and ensure excellent cross-regulation accuracy, to enable the longer operating lifetime, high performance and reduced cost required for white goods applications.
The output is designed to smoothly start-up into large capacitors, while maintaining a quick turn-on time. It operates in quasi-resonant mode to optimize efficiency and incorporates a low-power mode that achieves <30mW of no-load power consumption to meet global energy efficiency regulations.
