Test Procedure for the LV52206XAEVB Evaluation Board
Input Voltage
2.7~5.5V
voltage
Over Voltage
Protection
38V
Oscillation Frequency
600kHz
1. Please input "High" into SWIRE PIN during the period that is longer than Ton(20uSec) to start IC.
2. Then, please select a mode during mode select period(Tsel) .When you select Digital Mode, please input
"Low" longer than Tw1 after "High" longer than Tw0(100uSec) within Tsel(1mSec) period. It becomes PWM
mode if you fail to set Digital mode in specified timing period.
In the case of PWM frequency is less than 6.6kHz, it may become Digital Mode when you input a narrow
pulse of Duty.To evade it, input "High" that is longer than Tsel(2.2mSec), and, please input PWM pulse
afterwards.
3. IC shut down when you make SWIRE PIN Low longer than Toff(8.9ms) period.
The Data register is stored at this point. The reset of the power supply is necessary to clear it. In addition,
the mode is initialized when you shut down IC. Please make mode select each time you reboot.
