Controller IC Chip - RICHTEK RT8209MGQW RT8209M A5=DC A5=EC A5=CK A5=DF A5=DB A5=DD QFN-14 chip for laptop

The RT8209L/M PWM controller offers high efficiency, excellent transient response, and high DC output accuracy necessary for converting high-voltage batteries to low voltage for the CPU core, I/O, and RAM chipset supplies in laptops.

Fixed on-time PWM control easily manages wide input/output voltage ratios and provides immediate 100ns response to load transients while maintaining relatively constant switching frequency.
