数据: UCC28C4x-Q1 Automotive BiCMOS Low-Power Current-Mode PWM Controllers 数据表
UCC28C4x-Q1系列器件是高性能电流模式PWM控制器。它们是增强型BiCMOS版本,与行业标准UC28C4x系列PWM控制器具有引脚兼容性。
提供控制固定频率,峰值电流模式电源的必要功能,该系列具有多种性能优势。这些器件提供高达1 MHz的高频工作,启动和工作电流较低,从而最大限度地降低了启动损耗和低工作功耗,从而提高了效率。这些器件还具有快速电流输出,输出延迟时间为35 ns,具有±1 A峰值输出电流能力,可直接驱动大型外部MOSFET的上升和下降时间。
UCC28C4x-Q1系列是采用8引脚SOIC(D)封装。
