UCC2800 /1/2/3/4/5系列高速,低功耗集成电路包含所需的所有控制和驱动器组件用于离线和DC-DC固定频率电流模式开关电源,器件数量最少。
这些器件具有与UC2842 /3/4/5系列相同的引脚配置,并提供内部全周期软启动和电流检测输入的内部前沿消隐的附加功能。
UCC2800 /1/2/3/4/5系列提供最大占空比和临界电压水平。较低的参考部件(如UCC2803和UCC2805)最适合电池供电系统,而UCC2802和UCC2804的较高参考电压和较高的UVLO迟滞使其成为离线电源的理想选择。
符合JEDEC和行业标准的元件认证,确保在扩展温度范围内可靠运行。这包括但不限于高加速应力测试(HAST)或偏压85/85,温度循环,高压釜或无偏HAST,电迁移,键合金属间寿命和模塑化合物寿命。此类鉴定测试不应被视为超出规定的性能和环境限制使用该组件的合理性。
