7 / 13 page  AIC3643 7 BLOCK DIAGRAM CC RC RS M1 - + PWM Comparator 28V OVP Over Voltage Comparator - + 100mV VIN FB VREF + - Error AMP GND SW PWM/PFM Control SHDN Driver + - Current AMP. Control Logic 1.2MHz Oscillator Slope Compensation PIN DESCRIPTIONS PIN 1: SW - Switch pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI. PIN 2: GND - Ground pin. Tie directly to local ground plane. PIN 3: FB - Feedback pin. Reference voltage is 100mV. Connect cathode of lowest LED and resistor here. Calculate resistor value to obtain LED current according to the formula: RFB = 100mV/ILED PIN 4: SHDN - Shutdown pin. Tie to higher than 1.5V to enable device, 0.3V or less to disable device. PIN 5: OVP - Overvoltage protection. When VOUT is greater than 28V, the internal MOSFET turns off. PIN 6: VIN - Power input pin. Bypass VIN to GND with a capacitor sitting as close to VIN as possible. |
