AIC1630 2-Cell, Step-Up DC/DC Converter Controller FEATURES Adjustable Output Voltage with Two Resistors (AIC1630A).
Power-Saving Shutdown Mode (7µA typical).
120KHz Switching Rate.
On-Chip Low Battery Detector.
DESCRIPTION The AIC1630 is a DC-DC converter designed to drive an external power switch for more flexibility, especially in higher voltage and larger power applications.
Typically six components are required to set up a step up configuration easily achieving efficiency beyond 80%.
A few more components are required to set up a step down configuration delivering 4A load current with 83% typical efficiency, 86% at 2A load, and 300µA quiescent current.
The output voltage is internally ...
