波谷电流模式回授控制降压转换器

A4403 是使用波谷电流模式控制的降压转换器。此控制方案可以实现极短的导通时间，因此是需要高切换频率与高输入电压结合低输入电压应用的不二之选。\n\n高达 2 MHz 的切换频率允许使用低值电感器和电容器，因此可以降低成本。此外，由于集成度较高，因此所需外部组件数量很少。使用优化驱动电路显著降低切换损失。\n\n由于导通时间由输入电压调制，因此切换频率可以保持恒定。这种前馈控制可以确保出色的线性校正效果。导通时间由输入电源的外部上拉电阻设定。\n\n初始施加电源并启用器件后，会提供用户可配置的软启动功能，可以减少浪涌电流，并防止输出过冲。提供内部管理和自举电源，并且只需增加一个小型陶瓷电容器 • 最小输出电压变化量实现极快的负载瞬态反应\n• 导通时间小于 50 ns，获得高降压比\n• 用户可配置导通时间，可获得高达 2 Mhz 的转换频率\n• 只需使用最少的外部组件\n• 优化低值滤波电容器和电感器\n• 宽输入电压范围：9 至 46 V\n• 输出电流：3 A\n• 低待机电流 <100μA\n• 采用热增强型 QFN 封装;
