Part Number: TPS61158 Hello,
I have question regarding the parameter on the datasheet.
TPS61158 datasheet Figure 8 shows the timing diagram for startup and shutdown for the PWM mode, but I can't find the values for the startup delay, FB ramp and shutdown…
Part Number: TPS61166 Other Parts Discussed in Thread: TPS61158 Hi team,
I'd like to check about dimming method for TPS61166 and TPS61158.
I think that TPS61166 employs PWM dimming, and TPS61158 employs analog dimming by PWM signal. Is my understanding…
Part Number: TPS61158 Hi Team,
My customer wants to use 10kHz PWM frequency for dimming if possible. We are understanding our recommendation is 20k~100kHz for CTRL control though, what side effect will be expected if they use the lower frequency for CTRL…
Part Number: TPS61158 Dear TI Team,
This is an extension of the question linked below.
In Open Load, Open Load Protection does not seem to work as shown below.
I'm still having trouble, and I want to check if there is a problem with my circuit implementation…
Part Number: TPS61158 Other Parts Discussed in Thread: TEST Dear TI Team,
The TPS61158 is designed and in use. VCC: 5V Vout: 18V LED Load: 10mA
In the process of producing and testing the board, Anode / Gnd is measured by the tester with no load on the output…
Part Number: TPS61158 Other Parts Discussed in Thread: TPS61161 Hi,
My customer is using TPS61158 as a driver led for a backlight.
I can't find on the TI simulator to understand if in standard conditions (3V3, 20mA, 35 ° C) there can be particular criticalities…
Part Number: TPS61158 Other Parts Discussed in Thread: TEST Hi
We use the TPS61158 in PWM mode in one of our products as display backlight driver. The PWM signal is 50kHz and varies between 2...100%. In general, the device works as expected but we sometimes…
