Part Number: TPS61169 Hi team,
Can you have look at the following customer inquiry please?
In a current project I used the TI TPS61169 to drive a display backlight. The driver worked without problems in the pre-series, but currently we are struggling…
Part Number: TPS61169 Hi,
Can I use TPS61169 for following specification,
VIN= 5V
Vout(max)= 15.2V
Iout(max)= 100mA
CCM
Please also suggest the inductor value for this design using TPS61169.
Part Number: TPS61169 There are another 11 LEDs in series (12 toral - set to 50mA max wire 3R9)
The LIGHTS net is direct from a 1.8V CPU, and voltage goes rail to rail (checked on scope). When we run the PWM at around 500Hz (way below the spec) , the…
