Lenovo YOGA S730-13IML Wistron LS731 CML 19726-1 Schematic
Technical Specifications
Technical Summary
This Wistron S731-1 schematic, dated June 27, 2019, documents a Comet Lake (CML) platform motherboard with project code 4PD0FD01A001 and PCB P/N 19726 revision -1. The platform utilizes an Intel ComtLake QS PCH paired with a CPU identified as CPU1DWHISKEY-LAKE-GPZZ.00CPU.271. System memory consists of four LPDDR3 modules configured in dual-channel architecture operating at 2133MHz. The embedded controller is an uvoton KBC. Audio is handled by a Realtek ALC3268 codec with a TAS5766M smart amplifier. Power management includes an ISL9538HRTZ battery charger/selector and multiple DC/DC converters including SY8288CRAC, RT9610BZQW, RT3602AJGQW, NCP81218MNTXG, RT5797ALGQW, APL5934KAI, AOZ5038QI-05, G5388K11U, and RT8237CZQW. Storage connectivity is provided via an M.2 2280 SSD interface. The system includes an Intel Alpine Ridge DpSMBUS Thunderbolt controller, an RTS5455 USB Type-C PD controller, a PS8713 USB 3.0 re-driver, and an M.2 2230 WLAN module. A Hall sensor is present for thermal management.
