Since “9892” is generic, I have assumed this is for a High-Efficiency Synchronous Buck Converter (Voltage Regulator) , a very common type of IC. If your 9892 is a different component (e.g., sensor, MCU, amplifier), please let me know, and I will rewrite it.
The MY-9892 is a 2000W AC voltage regulator module utilizing a BTA16-600B triac for dimming, motor speed control, and heating regulation. It operates with an input of 110V-220V and provides an adjustable output of 50V-220V, suitable for resistive loads. For more technical details, visit Besomi.

The top thermal metrics help you calculate if you need a heatsink. From the my 9892 datasheet: Since “9892” is generic, I have assumed this
Since I can’t browse the live web, I’ll give you the most practical, datasheet-focused guidance based on common 9892-series ICs (e.g., CS9892, AD9892, or a CMOS 9892). If you clarify the manufacturer (Analog Devices, Cirrus Logic, etc.), I can be more precise. It operates with an input of 110V-220V and
