Part Number: TPS61158 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 get returns from customers where…
Part Number: TPS61158 Hi Sir,
We need a boost mode LED driver, please find the specification on below.
1. Vin is a 3v Lithium Battery.
2. Vf of LED is 3.5V.
3. ILED is 30mA.
I saw there is a 2-8 LEDs application on the datasheet. May I know TPS61158…
Part Number: TPS61158 Other Parts Discussed in Thread: INA139 Is it possible to attach a INA139 (Hi-Side Current Shunt Monitor) parallel to the feedback resistor of the TPS61158 WLED driver as shown below?
I'd like to use PWM for Dimming and need to…
Part Number: TPS61158 If there is a short across the LEDs (therefore Vout is shorted to FB) how will the part react? What voltage do you expect at Vout?
Part Number: TPS61158 Hi,
I have VIN at 5V and CTRL at 0V but see 4.4V at Vout. I was expecting 0V at Vout. Does this make sense? When CTRL is high (3.3V) I see ~18V at Vout which is appropriate for our application.
Thanks,
Chris

Part Number: TPS61158 Hi all,
Our customer wants to know turn on/off delay time for TPS6118.
Could you pls help to this?
It is difficult to find this in the datasheet.
1. Start up time?
2. FB ramp time?
3. shutdown delay time?
