前言

随着消费者对便携性和高效充电的需求增加,手机厂商和充电器品牌纷纷推出小型化PD快充产品,以满足市场需求。小型化PD快充不仅适用于手机充电,还可广泛应用于其他电子设备,如笔记本电脑、平板电脑等,为用户提供更加便捷的充电体验。而PD快充小型化得益于技术创新,如采用集成合封氮化镓(GAN)技术,提高能量转换率,高集成合封度IC减少外围元器件数量(约8颗组件),从而实现小巧体积与提高系统可靠性。rnuednc

通嘉PD快充解决方案

通嘉科技推出新一代高效率、高整合型PD Total Solution解决方案之LD968/9x+LD8528D+LD6935A333, 产品覆盖 45W 到 65W 功率等级范围,高集成度加高性能让IC在操作上可满足PD输出电压变化应用,同时也大幅度提高功率密度来符合市场小型化需求,下文将详细介绍这三颗IC特色。rnuednc

主控LD968/9x 采用混合模式(CCM+QR) 工作且内置E-Mode或D-Mode GaN,低压重载时可以操作于连续(CCM)模式(65/ 85/ 100KHz)提高带载能力,准谐振模式(QR)工作频率最大到达227KHz,以及外部可调整式过温度保护机制(External OTP), 并符合单层、双层PCB加工工艺。IC在不同输入电压、输出电压以及输出功率的情况下,自适应切换最佳频率操作模式,以提高系统工作效率。无论是对于美国能源局所订定的规范(US DOE Level VI)或是欧盟发布的法规(EU CoC Tier-2),都可以符合新能源法规。rnuednc
