AIC1631中文资料2-Cell, 500mA, Step-Up DC/DC Converter数据手册AIC规格书

描述 Description

DESCRIPTION
The AIC1631 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 AIC1631A. Efficiency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages.FEATURES
High Efficiency 90%.
Adjustable Output Voltage with Two Resistors (AIC1631A)
Power-Saving Shutdown Mode (7µA typical).
Internal 2A Switch.
120KHz Switching Rate.
Adjustable Switch Current Limit.
On-Chip Low Battery Detector.APPLICATIONS
Palmtop & Notebook Computers.
Pocket Organizers.
Cameras.
Pagers.
Battery Backup Supplies.
