This is gold. The manufacturer shows exactly how they tested the 9892. Use this topology as your starting point – especially for input/output capacitors (ESR requirements are critical for LDOs).
In a 4-pin DIP or SOP package, “9892” often corresponds to a with a CTR (Current Transfer Ratio) of 50-200%. You will see this in isolated power supplies or microcontroller input protection circuits. my 9892 datasheet
The MY-9892 is built around a thyristor (triac) circuit, typically utilizing the BTA16-600B Specification Input Voltage AC 110V – 230V Output Voltage Range AC 50V – 220V (Adjustable) Maximum Power 2000 Watts Maximum Current 8A (Peak up to 25A) Control Method Pulse Width Modulation (PWM) / Phase Control Circuit Board Material High-temperature resistant FR-4 Key Features Thermal Management : The module includes an integrated heatsink This is gold
While rated for 2,000W, users are advised to use active cooling (like a small fan) or derate the module to 1,000W for continuous operation to prevent the triac from overheating. In a 4-pin DIP or SOP package, “9892”
The (often listed as just 9892 ) typically refers to a popular, low-cost 2000W AC Voltage Regulator module used for dimming lights or controlling motor speeds. MY-9892 AC Voltage Regulator Datasheet
