RT8003为内建P-通道 与 N-通道 功率级MOSFET 开关组件的PWM同步降压型DC/DC转换器,输入范围2.4V至5.5V,可输出电流达600mA。RT8003适用于由单一锂电池或镍氢/镍镉电池供电的可携式电子装置。RT8003由于操作在PWM固定2MHz的切换频率,可适用较小的 CIN, COUT 电容与电感组件的设计,并内建两组低RDS(ON) 分别为高端230mΩ 与低端180mΩ 的MOSFET开关组件,减少电路板中所需的设计面积,只需加入电阻、电容与一个电感组件即可完成设计,另包含内建的缓启动机制、电路致能控制、过热与过电流保护等功能。RT8003采用小型可节省电路设计面积的VDFN-10L 3x3的封装。
