Overview
... white LED backlighting for medium to small size LCD panels.
It is a highly integrated step up DC-DC converter with input voltage range from 2.
7V to 25V, accommodating 1-, 2-, 3-, or 4-cell lithium ion batteries or 3.
3V, 5V, 12V or 20V regulated supplies.
The AOZ1934/5 integrates a 40V power MOSFET as well as compensation and soft start circuitry, which results in a simpler and smaller solution with much fewer external components.
A high switching frequency (800kHz) allows the use of a smaller inductor and capacitor to further reduce the solution size.
Each of the regulated current sinks in the AOZ1934/5 provides 20mA factory programmed current.
With a maximum of 40V at the output of the ste...
