Part Number: TPS61185 Other Parts Discussed in Thread: TPS61177A , TPS61187 , , TPS61183 From customer test result, the boost output voltage is OVP voltage when no LED is attached. It seem not match with D/S.
Is it normal? Thanks.
Is the behavior the same…
What I didn't see in your request was input supply voltage, so I will list a few alternatives which can support multi-strings in the same IC.
TPS61150A - Dual Output Boost WLED driver (single inductor)
TPS61183 - 6 channel
What type of dimming, PWM or analog do you prefer?
If you want precise matching of the LED current per string, then I suggest one of the TPS61181/2 or TPS61183 with 3 of the strings disabled. Using those parts, you will need to apply a separate 5V to…
