描述 Description
The iW1820 AccuSwitch™ digital PWM controller integrates a highly accurate control circuit with an 800V bipolar junction transistor (BJT) power switch to provide a complete solution for off-line power conversion at up to 15W of output power.
Renesas' 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.
特性 Features
• 15W Output, Optimized for 5Vout
• AccuSwitch™ - Integrated 800V Power BJT
