RT7202K 是一款简单且灵活的多用途 USB PD 控制器。透过程式设定，它可作为 source 或 sink 运作。</br>当作为 source 使用时，可用于离线式 AC-DC 转换器，因其整合了分流稳压器、恒压 (CV) 与恒流 (CC) 控制回路，并具备可程式化参考电压，可符合可程式化电源供应器 (PPS) 规范。当搭配外部降压或升降压控制器时，可构成 DCDC 转换器，例如车用充电器，并同样可符合 PPS 规范。当作为 sink 使用时，它简单、低成本且使用灵活，可向 source 请求所需电力。若使用 RT7202KD/KJ/KT/KS 进行 sink 设计，其具备 I<sup>2</sup>C 介面与两个 GPIO，可灵活运用，并可轻易由扮演 master 角色的其他 MCU 控制。</br>建议接面温度范围为 −40°C 至 125°C，环境温度范围为 −40°C 至 105°C。
