Part Number: TPS61169 Dear TI Team
I would like to confirm the output current regulation of TPS61169. The TPS61169 web page states that the Current per LED value is 400mA, but the electrical characteristics of the data sheet do not have a parameter that…
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, Support Team
A customer is designing an e-book.
I want to operate the Back-light LED using the following products,
As a result of checking, it seems that the number of strings is recommended as 10.
The customer's spec is…
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…
Part Number: TPS61169 Hi Team,
My customer got a few questions about TPS61169. Could you help guide me to the answers?
1. The attached TSC file is TPS61169 tsc file downloaded from ti.com but with inductor changes to 10uH. The IL seems not stable. Is…
