Hello Team ,
We are using TPS61169 is below condition :
No of IR LED : 2
IR LED Forward Voltage : Min 1.2V and MAX 1.7V
Current Setting : 300mA
Booster Input Voltage : 3V3
A. When Driver is enable we measured below voltage and current :
Booster Input Current : 372mA
Booster Output Voltage : 3V
Booster Output current : 304mA
Two LED is working but in that case booster works in VIN>VOUT condition .so let me known have this condition will effect the booster operation and how we will avoid this condition .
B. When Driver is disable we measured below voltage and current :
Booster Input Current : 126mA
Booster Output Voltage : 2.78V
Booster Output current : 125mA
When driver is disable then also LED is ON and 125mA current will flow.we need a solution that will off the LED in driver disable condition .
Please provide the some solution two solve above two issue
we are waiting for your response .
