Other Parts Discussed in Thread: TPS92380
Dear TI support team,
I wanted to raised a question about the TPS61169. In the datasheet, it is explain that the minimum dimming value is 1%. We are trying to design a circuit that goes further down to 0.1%. My question is if there is another equivalent IC (led driver) that can be used. The dimming concept suits our application, I mean providing the PWM to the IC and creating the analog dimming is correct for our application. We want to avoid external components to produce the dimming control from 0.1% to 1%, so looking for an integrated solution. The device needs to boost the voltage in nominal conditions from 4.2V to 11.44V, of course with an input range (ex: 3 to 6Vdc). A current of 300mA can be used as a reference.
Please let me know in the case that my question is not clear, so I can provide more details.
Thanks in advance
Diego Alegre
