AIC1631 - 2-Cell/ 500mA/ Step-Up DC/DC Converter

Datasheet Summary

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.

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.

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. Pocket Organizers. Cameras. Pagers. Battery Backup Supplies.
