Part Number: TPS61166 Other Parts Discussed in Thread: TPS61500 Tool/software:
We use it in endoscope headend lighting, which is related to CMOS exposure and has 30HZ application scenarios.
1. Regarding the drive current range and PWM frequency limitation…
Part Number: TPS61166 LED Driver team,
I see the spec in the datasheet for Isd (Shutdown current) at 1 uA. I believe this is the current into Vin and Vbat when EN = 0. Can you tell me how much current will be going into the SW pin when EN=0?
In this customer…
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: TPS61166 Other Parts Discussed in Thread: TPS61169 Hi,
Application: To drive4 IR LED connected in series using TPS61166 . Combined Vf of four led - 6V, LED drive current is set to 400mA
Issue:
When the LED is not connected to the driver, the…
Part Number: TPS61166 Hi Sir:
The FB voltage is 0.2-V , LED current was programmed by R1 resistor. What will happened when I set the current is 120 mA and use PWM 100 % but the panel BL module only accepts maximum current is 50 mA ? Does it damage the…
Part Number: TPS61166 Hi,
I am debugging a problem that I didn't antecipate ever happening.
I am seeing VFB at about 370mV, which in turn makes my current turn into 37mA.
I used a 10R resistor.
Any ideas why this is happening?
Part Number: TPS61166 Hi,
if customer operate the device for a long time (min. 5-6 hours) with 0% PWM (LOW) they have the problem that the IC (afterwards) is not able to provide power/voltage to supply the LED`s until they re-power the IC. Is that known…
Part Number: TPS61166 Other Parts Discussed in Thread: TPS61158 Hi,
We are planning to use TPS61166 LED Driver in our design. The input voltage range for the LED Driver in our design is from 3.3V to 4.2V (running off a single-cell Li-ion Battery). As…
Part Number: TPS61166 Hello team,
I'd like to know what the part number of the LED material mounted on the TPS61166 EVM. I looked for it, but there is no description on the Bill of Materials. (Table 2 on the SLVU326) Could you tell the material information…
Part Number: TPS61166 Hello application team,
I have a question about TPS61166.
How the charge on VO boosted is discharged when OVP is asserted? From the block diagram on the datasheet, there is no discharge circuit seen on the VO. Is the charge stayed…
