Tool/software:

Hi Sir,

Could you share the PWM dimming duty accuracy when TPS923652 is working at the below conditions?

VIN= 5 V, VLED=12V, ILED=100mA.

PWM frequency=10kHz, PWM duty cycle at 3~100%.

PWM signal voltage level: 3.3V(H), 0V(L).

Could you share the PCBA size info(W*L*H) for TPS923655DMTREVM?

Hi Henry,

What is the meaning of "dimming duty accuracy" that you mentioned? Do you want to mean dimming accuracy?

For the TPS923655DMTREVM, the width is 87.63 mm, the length is 101.50 mm. What is the meaning of "H" that you mentioned? Do you want to mean the thickness of the board? Or do you want to mean the overall height of the PCBA including the standoffs and other components?

Best Regards,

Steven
