DESCRIPTION
The AIC1633 is a high efficiency step up DC/DC converter. Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V. The output voltage can be externally set to an arbitrary value below breakdown voltage of the power switch for AIC1633A. Efficiency beyond 83% can be easily achieved at 70mA load with 2.2V to 3V input voltages.

FEATURES
• High Efficiency Up To 87%.
• Adjustable Output Voltage with Two Resistors (AIC1633A)
• Power-Saving Shutdown Mode (7µA typical).
• Internal 0.8A Switch.
• 120KHz Switching Rate.
• Adjustable Switch Current Limit.
• On-Chip Low Battery Detector.

APPLICATIONS
• Pocket Organizers.
• Electronic Dictionaries.
• Cameras.
• Pagers.
• Bar-Code Scanners.
• LCD Displays.
• Battery Backup Supplies.
• Portable Instruments.
