Short Description: High-performance Richtek RT8237CZQW (top marking: Z3) single-phase synchronous step-down PWM controller IC in a compact 10-pin 3x3 WQFN package. Designed for stepping down main battery or adapter rails to generate low-voltage CPU core, chipset, system I/O, or DRAM power rails (e.g., $+1.05\text{V}$, $+1.35\text{V}$, $+1.5\text{V}$, $+1.8\text{V}$) on laptop motherboards. Utilizes Constant On-Time (COT) control to deliver instant load-step response while driving large external high-side and low-side N-Channel MOSFETs. Essential component replacement for repairing laptop power supply stages, fixing missing RAM or chipset supply rails, and replacing shorted PWM controllers.
