Detailed pinouts for the PWM (Pulse Width Modulation) controllers that step down the 19V adapter voltage to the lower voltages needed by the CPU and RAM.
Q: What is the purpose of the 10203-1 schematic? A: The 10203-1 schematic provides a detailed technical drawing of an electronic component or system, serving as a guide for design, building, and troubleshooting.
This section handles the video signal to the display. Technicians use this to troubleshoot "no backlight" or "no display" issues by checking for the GFX_PWR_SRC signal on pins 28–30. 10203-1 schematic
| Pin Number | Signal Name | Description | |------------|-------------|-------------| | 1 | VCC (12-48V) | Power input for the internal controller | | 2 | GND | Power and signal ground | | 3 | CURRENT_SENSE | Input from external shunt resistor (0V to 1V max) | | 4 | OSC_R | Connects timing resistor to ground | | 5 | OSC_C | Connects timing capacitor to ground | | 6 | COMP | Error amplifier output (for frequency compensation) | | 7 | VFB | Voltage feedback input from secondary side via optocoupler | | 8 | REF | 5V reference output (max 10mA) | | 9 | SOFT_START | External capacitor to GND for soft-start (typ. 10µF) | | 10 | SYNC | Synchronization input (for parallel operation) | | 11 | VIN_SENSE | Input voltage monitoring (for brownout protection) | | 12 | NC | Not connected | | 13 | RT1 | Thermistor input (for thermal shutdown) | | 14 | GATE_DRV | PWM output to external MOSFET gate | | 15 | VOUT_SENSE | Remote sense for output voltage | | 16 | GND_SENSE | Kelvin ground for sense circuit |
