From the project
Potentiometer-controlled LED dimmer board
Potentiometer-controlled high-current LED dimmer (TLC555 PWM + LM358 + IRF540N MOSFETs)
- Status: Routed - Board size: 103 x 74.2 mm - Layers: 2 - Components: 42 - Key ICs: - U1: L7805 - U2: TLC555CDR - U3-U5: LM358M
- TLC555CDR (U2) - CMOS 555 timer wired as the PWM oscillator; sets switching frequency - LM358M x3 (U3-U5) - dual op-amps used for the pot-to-duty-cycle conversion and gate drive shaping - IRF540N x5 (Q1-Q5) - power N-channel MOSFETs that switch the LED string current; five in parallel for high total throughput - L7805 (U1) - linear 5 V rail for the analog/control side - POT…
