Part Number: TPS92612

Hi,

TPS92612 specification is not clear for me.

Could you please define which kind of input PWM is? Can I use it directly by MCU's GPIO/PWM-output?

IO-level point of view it is ok but is there any internal pull up/down or what is input impedance of it?

Supply current in active mode is not defined? Only standby current is defined. What is current consumption in active mode?

Hi Markku,

Yes, you can use it directly by MCU's GPIO/PWM-output. For the PWM IO pin, it has an internal pull-down resistor with high impedance. There is no meaning for the supply current since for such kind of linear LED driver, the voltage will all drop on the device and the supply current(~mA) is very low compared with the output current.
