Package: 16-pin DIP
Duty cycle: up to ~45–49% per output
Temperature range: 0°C to 70°C (industrial versions vary)
🔌 Pin usage (important idea)

Typical blocks:

SD6835 – SILAN (Silan Microelectronics) is a high-voltage offline switch-mode power supply (SMPS) controller with an integrated MOSFET.

It is a primary-side flyback power IC, commonly found in LED drivers, chargers, and small SMPS adapters.

Silan Microelectronics SD6835 is a current-mode PWM + PFM controller with a built-in high-voltage (650 V) MOSFET, meaning it can directly switch AC mains without an external power transistor.

So in simple terms:
👉 It is an all-in-one SMPS switching IC

⚙️ Key electrical characteristics
Built-in MOSFET voltage rating: 650 V
Controller type: Current-mode PWM + PFM
Start-up current: very low (~4 µA class)
Operating frequency: ~25 kHz to 67 kHz (load dependent)
Topology: Flyback converter
Package: usually DIP-8 / SOP-8 variants
Power range: typically up to ~20–25 W adapters

;- PIC12F508-I/P is an 8-bit Flash microcontroller from Microchip Technology, commonly used in small embedded control applications.

Key specifications:

Core: 8-bit PIC
Program Memory: 768 bytes (512 × 12-bit Flash)
RAM: 25 bytes
Operating Voltage: 2.0 V to 5.5 V
Internal Oscillator: 4 MHz
I/O Pins: 5
Timer: 1 × 8-bit Timer0
Watchdog Timer: Yes
Package: PDIP-8 (I/P = Industrial temperature range, Plastic DIP)
Operating Temperature: −40°C to +85°C

Common applications:
Power supply control
LED lighting controllers
Battery chargers
Home appliances
Remote controls
Small automation systems

Programming:
The PIC12F508-I/P is a Flash-programmable device and can be programmed using PICkit 3, PICkit 4, PICkit 5, or compatible programmers via ICSP (In-Circuit Serial Programming).

If you're repairing a circuit and found a PIC12F508-I/P, keep in mind that it contains application firmware. Replacing it with a blank chip will not restore operation—you'll need the correct firmware programmed into the replacement device.

;- IRF540N is a widely used N-channel enhancement-mode power MOSFET for low- to medium-voltage switching applications.

Typical specifications:

Type: N-channel MOSFET
Drain-Source Voltage (VDS): 100 V
Continuous Drain Current (ID): 33 A (at 25°C case temperature)
RDS(on): 44 mΩ max @ VGS = 10 V
Gate-Source Voltage (VGS): ±20 V
Power Dissipation: Up to 140 W
Package: TO-220AB
Pinout: 1 = Gate, 2 = Drain (also the metal tab), 3 = Source.

Common applications:

DC motor control
Battery-powered inverters
DC-DC converters
Power switching
Solenoid and relay drivers

Important note:
The IRF540N is not a logic-level MOSFET. Although it begins to turn on at a gate-source voltage of around 2–4 V, it requires about 10 V on the gate to achieve its specified low on-resistance. If you're driving it directly from a 3.3 V or 5 V microcontroller (such as an Arduino or ESP32), it may not switch fully on and can overheat.
