Part Number: TPS92201A According to the datasheet. PWM Dimming range is 1% ~100% Is there any issue occurred when PWM 0% (stop the PWM signal and set to Low) and EN is high?
Part Number: TPS92201A Hello,
I am developing a handheld device that utilizes three TPS92201A LED drivers with their EN pins tied together. I am encountering an issue where I cannot fully turn off the LED output, while keeping the EN pin enabled.

Part Number: TPS92201A I'm now designing with TPS92201A to drive 4 parallel LED (max current is around 80mA). If I place the 0.1uF capacitor in parallel with 4 LEDs, is there any concern with this?
Part Number: TPS92201A Other Parts Discussed in Thread: TPS92201 , TLV62568 Dear TI team, to drive a LCD backlight i would like to use the TPS92201A. (60mA@3V). Supply=5V. But i can not quite follow the "Application and Implementation" in the datasheet…
Part Number: TPS92201A Other Parts Discussed in Thread: TPS92201 I'm looking at the TPS92201(A) for an application using color LEDs at 0.2A current---somewhat lower than the capability of this chip. I don't understand why the datasheet lists a maximum…
Part Number: TPS92201A Tool/software: There are two major issues in the TPS92201A datasheet :
Section 8.2.2.2 is copy-pasted from some other TI buck converter, and does not match anything else in the datasheet, and even specifies the feedback voltage…
Part Number: TPS92201A Other Parts Discussed in Thread: TPS92201 , , Tool/software: Hi, We have noticed that TPS92201 has dimming depth smaller than 100:1 (approximately 33:1). But TPS92201 A has 100:1. Could you please confirm the difference in behaviour…
Part Number: TPS92201A Tool/software: Hello,
I recently completed assembly of a design using TPS92201ADRVR. While my LEDs light up just fine, they seem to be at 100% brightness all the time and PWM dimming does not work. I'm unsure of what could cause…
Part Number: TPS92201A I was using WEBENCH simulator for TLV62585DRLR the other day but then found TPS92201A is more suitable for my application but I wanted the simulation and calculation. Why there is no webench support for TPS92201A?
Part Number: TPS92201A Hi experts,
My customer consider to use TPS92201A for low current such as 5mA~7mA.
Is it possible to operate stably in PFM mode even with such a low current?
Also, if there is an efficiency curve or measurement data for light…
