Connect a 0.47 µF capacitor (C1) between C1+ and C1–. C1+ (Pin 2): First Charge Capacitor Positive Input. Connect a 0.47 µF capacitor (C1) between C1+ and C1–. C2– (Pin 3): Second Charge Capacitor Negative Input. Connect a 0.47 µF capacitor (C2) between C2+ and C2–. C2+ (Pin 4): Second Charge Capacitor Positive Input. Connect a 0.47 µF capacitor (C2) between C2+ and C2–. VCC (Pin 5): Positive Supply Input. 4.75V ≤ VCC ≤ 5.5V. Requires a 10 µF bypass capacitor to ground (C4). VOUT (Pin 6): 12V Output. Requires a 10µF or a higher value bypass capacitor to ground (C3). VOUT = VCC when in the shutdown mode. GND (Pin 7): Ground. SHDN (Pin 8): Active-High TTL Logic Level Shutdown Pin. SHDN is internally pulled up to VCC. Connect to GND for normal operation. In shutdown mode, the charge pump is turned off and VOUT = VCC. Output Voltage TEMPERATURE ( °C) –55 105 LTC1263 • TPC02 –15 25 65 12.8 12.6 12.4 12.2 12.0 11.8 11.6 11.4 11.2 –35 5 45 85 IOUT = 0mA IOUT = 90mA IOUT = 60mA VCC = 5V |
