AIC1631
2-Cell, 500mA, Step-Up DC/DC Converter
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.
DESCRIPTION
The AIC1631 is a high efficiency step up DCDC 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.
APPLICATIONS
Palmtop & Notebook Computers.
