TPS922052: operate at 100% output without a processor such as an MCU

Part Number: TPS922052

What should I do if I want to operate at 100% output without a processor such as an MCU?

If necessary, please tell me about the circuit and timing of ADIM/HD, EN/PWM, Vcc, etc.

Hi JOOHYEONG,

You can pull up the EN/PWM pin and ADIM/HD pin to the VCC pin to get an always-on and always-100%-amplitude output.

Best Regards,

Steven

I thought so too.
But I asked because it seemed that sometimes the light did not turn on during the ON/OFF test.

Best regards,
KIM.

Hi KIM,

Could you give me more detailed information about your description of "light did not turn on during the ON/OFF test"? For example, what is the circuit you used? What is your input voltage, LED voltage and current?

Best Regards,

Steven
