Short Description: High-efficiency Richtek RT8205LZQW (top marking: EM=) dual synchronous step-down PWM controller IC in a 24-pin WQFN package. Specifically designed to generate the primary $3.3\text{V}$ and $5\text{V}$ system standby power rails (3VALW / 5VALW) on laptop motherboards and embedded logic boards. Includes dual integrated low-dropout linear regulators (LDOs) to power embedded controllers (EC) and auxiliary power monitoring stages. Essential replacement chip for resolving dead motherboard issues, missing $3.3\text{V}/5\text{V}$ standby rails, short-circuit trips, and power-on failures.
