The MY-9892 does not function like a variable DC step-down converter. Instead, it relies on :
MY‑9892 is a compact, synchronous buck regulator designed for medium‑power DC–DC conversion. It integrates high‑side and low‑side MOSFETs and offers high efficiency across light to heavy loads, fast transient response, and robust protection features for portable and embedded applications.
These two chips work together like a high-performance audio system. my 9892 datasheet exclusive
