5 / 20 page  5 LTC3444 3444fb PI FU CTIO S SHDN (Pin 1): Shutdown Function. A logic low input shuts down the IC. A logic high input enables the IC and starts the internal soft-start function by limiting the rise time of the internal PWM command. SW1 (Pin 2): Switch Pin Where the Internal Switches A and B are Connected. Connect inductor from SW1 to SW2. An optional Schottky diode can be connected from ground to SW1 for a moderate efficiency improvement. Minimize trace length to minimize EMI. GND (Pin 3): Ground Pin for the IC. SW2 (Pin 4): Switch Pin Where the Internal Switches C and D are Connected. An optional Schottky diode can be connected from SW2 to VOUT for a moderate efficiency improvement. Minimize trace length to keep EMI down. VOUT (Pin 5): Output of the Synchronous Rectifier. A filter capacitor is placed from VOUT to GND. A ceramic bypass capacitor is recommended as close to the VOUT and GND pins as possible. VIN (Pin 6): Input Supply Pin. Internal VCC for the IC. A 4.7 μF ceramic capacitor is recommended as close to VIN and GND as possible. VC (Pin 7): Error Amp Output. Pull VC to ground to select internal loop compensation. External compensation may be connected from VC to FB. Internal compensation will be disabled if VC is tied to an external compensation network. FB (Pin 8): Feedback Pin. Connect resistive divider tap here. The output voltage can be adjusted from 0.5V to 5V. The feedback reference voltage is typically 1.22V. GND (Pin 9, Exposed Pad): Solder to Board GND. |
