The TPS22993 is a multi-channel, low RON load switch with user programmable features. The device contains four N-channel MOSFETs that can operate over an input voltage range of 1.0V to 3.6V. The switch can be controlled by I2C making it ideal for usage with processors that have limited GPIO available. The rise time of the TPS22993 device is internally controlled in order to avoid inrush current. The TPS22993 has five programmable slew rate options, four ON-delay options, and four quick output discharge (QOD) resistance options.

The channels of the device can be controlled via either GPIO or I2C. The default mode of operation is GPIO control through the ONx terminals. The I2C slave address terminals can be tied high or low to assign seven unique device addresses.

The TPS22993 is available in a space-saving RLW package (0.4mm pitch) and is characterized for operation over the free-air temperature range of –40°C to 85°C.

TIDA-00194 — 適用於 Intel SkyLake™ 處理器平台的電源調節與分配參考設計

TI 針對 Intel SkyLake™ 處理器平台的電源調節、分配和排序之最佳化解決方案。此設計運用高效率 DC/DC 切換穩壓器與整合式負載開關，展示了對四個獨特電源軌的穩壓，以及 21 個不同負載點的分配。透過四通道負載開關及高效率整合式 DC/DC 降壓式轉換器，可大幅縮減電路板面積。此外，混合 I2C/GPIO 控制可降低或消除 GPIO 需求，進而簡化 PCB 配置。此設計以 4.5V 至 15V 的輸入電壓範圍運作，模擬 2S/3S 鋰離子電池拓撲結構。基於 PC 的 GUI 透過標準 USB 纜線控制板載電源元件。  即時電源傳輸狀態回饋透過板載 LED 和 PC 圖形提供。
