Cxac8551as7g is a high-performance off-line PSR controller for low-power AC / DC chargers and adapters. Cxac8551 integrates a high voltage power supply of CMOS 600 V, 2. It operates on the primary side of sensing and regulation. Therefore, opto coupler and tc431 can be eliminated. In CC control, current and output power settings external detection resistor rs can be adjusted in CS pin. Resume control and PFM operation are used to achieve high performance and high efficiency. In addition, good load regulation is compensated by a built-in cable. The chip consumes very low operating current (typical 420 μ a). It can realize less than 50 MW standby power supply to meet the strict standby power supply standard.

产品概述 返回TOP
CXAC8551AS7G是高性能离线PSR控制器低功率AC/DC充电器和适配器的应用。CXAC8551集成了一个高压电源的CMOS 600 v,2。它运作在初级侧感测和监管。因此,opto-coupler和TC431可以消除。在CC控制、电流和输出功率设置可以调整外部检测电阻RS在CS销。简历控制、PFM操作是用来实现高性能和高效率。此外,良好的负载调节是通过内置的电缆补偿。芯片消耗非常低的操作电流(典型的420μa),它可以实现不到50mw备用电源以满足严格的备用电源标准。CXAC8551提供全面的保护范围,自动恢复功能,包括逐周期限流,VDD过压保护,反馈回路打开保护,短路保护,内置前沿消隐,VDD欠压锁定(UVLO)等。
