Part Number: TPS54201 Hello,
While I am trying to build a back signal light for bike using this chip in order to step-down the voltage from 12v battery and make sequencial dimming, would it be possible by only using one of this chip?
Thank you so…
Part Number: TPS54201 Hello,
While i was building circuit i found that i need pwm signal in order to step-down the voltage and use it for led driver.
This driver will be used as headlight and signal backlight of the bike. I tried to voltage divide…
Sean,
Thank you for your prompt reply. I understand that the regulator will turn off when the input goes below the LED's Vf.
Just to verify, the TPS54201 buck regulator has no stability problem with the high duty cycles (duty cycle of the 600kHz switching…
Part Number: TPS54201 Hi team,
As you know the PWM input of TPS54201 is multifunction, it is used for PWM/analog dim input, and also for PWM/analog dim mode configuration. To keep the device operate in PWM mode the amplitude of PWM signal should be…
Part Number: TPS54201 Hi Team,
My customer would like to use TPS54201 with both PWM Dimming and Analog Dimming in the same circuit.
During PWM dimming, the dimming frequency will be 250Hz, and duty cycle from 10% onwards, and the PWM signal amplitude…
Part Number: TPS54201 Hi team,
My customer would like to use TPS54201 device for LED driver. As it is buck architecture, is there any limitation between input voltage and output voltage? They would use 12V input, the load is 10 parallel LEDs (2V forward…

Hello, I want to simulate my circuit containing the TPS54201 in LTSpice, but the model for this part is encrypted, so I can't use it. Is it possible to get an unencrypted model for the TPS54201 or, if no, could you please suggest…
Part Number: TPS54201 Other Parts Discussed in Thread: LM3643 , LM36010 , LM3644 Hello,
I want to use the TPS54201 in analog mode command to dimming the power of the LED.
But, I want also blinking the LED at variable frequency (0 to 1000 Hz). Can…
Part Number: TPS54201 hi team,
my customer has a new requirement below input 10.8~13.2V, 3series led(each led voltage drop is 3.1v, total 9.3v),current is 1.5A.
Whether the TPS54201 is ok to be used here? especially for the thermal and voltage drop…
