Part Number: TPS92201 Tool/software: Hi TI team,
We plan to use TPS92201 to drive a single white LED. We don't need PWM dimming function, and there is no PWM pin available on our existing board.
In this case how should we deal with the PWM pin of…
Part Number: MSPM0G3507 Tool/software: Hi
The output voltage of PWM is defined by the VDDIO and change in this voltage will also change on the PWM voltage. In my application, I want my PWM voltage to be constant and change duty and frequency as per…
Part Number: DRV8256 Tool/software: Hi team,
I have questions regarding DRV8256 as follows: 1. For PWM control, is it mandatory to use IN1/IN2 pins instead of EN/PH pins? Would it not work properly if PWM is applied to the EN pin and direction is controlled…
Part Number: TPS22919 Tool/software: I am using part tps22919 as a load switch. If ON is low, a 10K resistor pulls VOut Low, disabling the output. If ON is high, I want to pass a PWM signal, around 20KHz, from In (pin 1) to Out (Pin 6). I am seeing that…
Part Number: TPS61196 Tool/software: Hi, I've shorted all PWM input pins from 1-6, and connected to a single driving pin to the STM32. I realized that when increasing the duty cycle to 100% the TPS61196 or the STM32 itself stopped working. ( need to check…
Part Number: TPS54620 Tool/software: Dear Sir,
I use this demo sch to control the laser led, I want to know what f requency of LED_PWM should be used? 1K or 10KHz? thanks.
Part Number: MSPM0C1103 Other Parts Discussed in Thread: MSPM0C1104 , SYSCONFIG Tool/software: I'm migrating a STM32 M0 core to the MSPM0C1104 for a SMPS control using PWM modulation on a 2 switch push-pull topology.
I need to update the duty cycle…
Part Number: MSPM0G3107 Other Parts Discussed in Thread: MSPM0G3507 , SYSCONFIG Tool/software: Hello,
I am working with the PWM peripheral to control some LEDs. During power-on I am expecting my LEDs to be off until a certain event happens in my software…
Part Number: LMR51450 Tool/software: Customer is considering LMR51450 and will evaluate with LMR51450EVM. Is there any way to use PWM mode with using LMR51450EVM? Since LMR51450SDRRR is on LMR51450EVM and this is only EVM for LMR51450.
Part Number: DRV8305-Q1 Tool/software: Hi Expert,
Have a nice day! I have question need your professional support:
I want to know how to choose BLDC’s Operating switching frequency? What factors determine the frequency?
Do you have any instruction…
