  其中,高频小尺寸的DCDC转换器由于其高效、可靠、节省空间等特性,在上述市场越来越受欢迎。

  DIO62820简介

  DIO62820是帝奥微推出的新一代高频高效、超小尺寸的600mA同步降压DCDC转换器,不仅能够提供高达5MHz的开关频率,同时允许使用尺寸为1.0mm x 0.5mm的1uH电感,以及0.6mm x 0.3mm的陶瓷电容作为输入电容CIN和输出电容COUT,有助于减少PCB面积及降低BOM成本。

  DIO62820支持PWM/PFM模式自动切换,它在轻负载时工作为非连续模式,可有效降低功耗,当负载较重时则自动切换到连续模式以便降低纹波电压及噪声。同时,DIO62820使用了支持高速瞬态COT的控制模式,可实现快速的瞬态响应和稳定的输出电压。
