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…
Part Number: TPS92201 In this post from eight months ago,
https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1562464/tps92201a-errors-in-datasheet-including-example-layout
it was claimed that the datasheet…
HI,
Do you have specific P/N that you used?
TPS92201 is FPWM mode which has lower eff at light load
TPS92201A has PFM mode to improve eff at light load condition
Ok, pls explain it to customer that At light load, only TPS92201A automatically enters pulse frequency modulation (PFM) to maintain high efficiency over the entire load current range, TPS92201 will keeps switching at 1.5MHz for smaller output ripple.
