Rm1-2316 Schematic =link= Jun 2026

| Block | Function | |-------|-----------| | | Connects to rectified DC (320V) via pin 8; provides initial charge to VCC cap. | | PWM Oscillator | Fixed frequency ~65 kHz (frequency jittering for EMI reduction). | | Current Sense Comparator | Monitors MOSFET source resistor via pin 3 (CS). | | Feedback Amplifier | Optocoupler input (from secondary side TL431) connects to pin 2 (FB). | | Soft-Start | Gradual increase of duty cycle at startup (pin 6 capacitor). | | Brownout Detector | Monitors bulk capacitor voltage via resistor divider to pin 5. | | Output Driver | Totem-pole output to external power MOSFET gate (pin 7). |

This shows a classic common-emitter or common-source amplifier with shunt feedback for stability. Rm1-2316 Schematic
