4.5V 至 30V 两相峰值电流模式同步降压控制器

The LM2642 consists of two current mode synchronous buck regulator controllers with a switching frequency of 300kHz.The two switching regulator controllers operate 180° out of phase. This feature reduces the input ripple RMS current, thereby significantly reducing the required input capacitance.
